This reverts commit 8c3ed7aa. As Jouni points out, there's really no need for this, since the RSN pre-authentication frames are normal data frames, not port control frames (locally). We can still revert this now since it hasn't actually gone beyond -next. Fixes: 8c3ed7aa ("nl80211: add src and dst addr attributes for control port tx/rx") Signed-off-by:

Andrew Lunn says: ==================== mv88e6xxx: Add SERDES/PCS registers to ethtool -d ethtool -d will dump the registers of an interface. For mv88e6xxx switch ports, this dump covers the port specific registers. Extend this with the SERDES/PCS registers, if a port has a SERDES. ==================== Signed-off-by: -
Andrew Lunn authored
The mv88e6390 has upto 8 sets of PCS registers, depending on how ports 9 and 10 are configured. The can be spread over 8 ports. If a port has a PCS register set, return it along with the port registers. The register space is sparse, so hard code a list of registers which will be returned. It can later be extended, if needed, by append to the end of the list. Signed-off-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2020-02-15 This series contains updates to ice driver only. Brett adds support for "Queue in Queue" (QinQ) support, by supporting S-tag & C-tag VLAN traffic by disabling pruning when there are no 0x8100 VLAN interfaces currently on top of the PF. Also refactored the port VLAN configuration to re-use the common code for enabling and disabling a port VLAN in single function. Added a helper function to determine if the VF link is up. Fixed how the port VLAN configures the priority bits for a VF interface. Fixed the port VLAN to only see its own broadcast and multicast traffic. Added support to enable and disable all receive queues, by refactoring adding a new function to do the necessary steps to enable/disable a queue with the necessary read flush. Fixed how we set the mapping mode for transmit and receive queues. Added support for VF queues to handle LAN overflow events. Fixed and refactored how receive queues get disabled for VFs, which was being handled one queue at at time, so improve it to handle when the VF is requesting more than one queue to be disabled. Fixed how the virtchnl_queue_select bitmap is validated. Finally a patch not authored by Brett, Bruce cleans up "fallthrough" comments which are unnecessary. Also replaces the "fallthough" comments with the GCC reserved word fallthrough, along with other GCC compiler fixes. Add missing function header comment regarding a function argument that was missing. ==================== Signed-off-by: -

Finn Thain says: ==================== Improvements for SONIC ethernet drivers Now that the necessary sonic driver fixes have been merged, and the merge window has closed again, I'm sending the remainder of my sonic driver patch queue. A couple of these patches will have to be applied in sequence to avoid 'git am' rejects. The others are independent and could have been submitted individually. Please let me know if I should do that. The complete sonic driver patch queue was tested on National Semiconductor hardware (macsonic), qemu-system-m68k (macsonic) and qemu-system-mips64el (jazzsonic). ==================== Signed-off-by: -
Finn Thain authored
On m68k, local irqs remain enabled while interrupt handlers execute. Therefore the macsonic driver has had to disable interrupts to avoid re-entering sonic_interrupt(). As of commit 865ad2f2 ("net/sonic: Add mutual exclusion for accessing shared state"), sonic_interrupt() became re-entrant, and its wrapper became redundant. Tested-by:

Sergei Shtylyov says: ==================== sh_eth: get rid of the dedicated regiseter mapping for RZ/A1 (R7S72100) Here's a set of 5 patches against DaveM's 'net-next.git' repo. I changed my mind about the RZ/A1 SoC needing its own register map -- now that we don't depend on the register map array in order to determine whether a given register exists any more, we can add a new flag to determine if the GECMR exists (this register is present only on true GEther chips, not RZ/A1). We also need to add the sh_eth_cpu_data::* flag checks where they were missing so far: in the ethtool API for the register dump. ==================== Signed-off-by: -
Sergei Shtylyov authored
The register maps for the Gigabit controllers and the Ether one used on RZ/A1 (AKA R7S72100) are identical except for GECMR which is only present on the true GEther controllers. We no longer use the register map arrays to determine if a given register exists, and have added the GECMR flag to the 'struct sh_eth_cpu_data' in the previous patch, so we're ready to drop the R7S72100 specific register map -- this saves 216 bytes of object code (ARM gcc 4.8.5).

Not all Ether controllers having the Gigabit register layout have GECMR -- RZ/A1 (AKA R7S72100) actually has the same layout but no Gigabit speed support and hence no GECMR. In the past, the new register map table was added for this SoC, now I think we should have used the existing Gigabit table with the differences (such as GECMR) covered by the mere flags in the 'struct sh_eth_cpu_data'. Add such flag for GECMR -- and then we can get rid of the R7S72100 specific layout in the next patch... Signed-off-by:

Russell King says: ==================== Pause updates for phylib and phylink Currently, phylib resolves the speed and duplex settings, which MAC drivers use directly. phylib also extracts the "Pause" and "AsymPause" bits from the link partner's advertisement, and stores them in struct phy_device's pause and asym_pause members with no further processing. It is left up to each MAC driver to implement decoding for this information. phylink converted drivers are able to take advantage of code therein which resolves the pause advertisements for the MAC driver, but this does nothing for unconverted drivers. It also does not allow us to make use of hardware-resolved pause states offered by several PHYs. This series aims to address this by: 1. Providing a generic implementation, linkmode_resolve_pause(), that takes the ethtool linkmode arrays for the link partner and local advertisements, decoding the result to whether pause frames should be allowed to be transmitted or received and acted upon. I call this the pause enablement state. 2. Providing a phylib implementation, phy_get_pause(), which allows MAC drivers to request the pause enablement state from phylib. 3. Providing a generic linkmode_set_pause() for setting the pause advertisement according to the ethtool tx/rx flags - note that this design has some shortcomings, see the comments in the kerneldoc for this function. 4. Remove the ability in phylink to set the pause states for fixed links, which brings them into line with how we deal with the speed and duplex parameters; we can reintroduce this later if anyone requires it. This could be a userspace-visible change. 5. Split application of manual pause enablement state from phylink's resolution of the same to allow use of phylib's new phy_get_pause() interface by phylink, and make that switch. 6. Resolve the fixed-link pause enablement state using the generic linkmode_resolve_pause() helper introduced earlier. This, in connection with the previous commits, allows us to kill the MLO_PAUSE_SYM and MLO_PAUSE_ASYM flags. 7. make phylink's ethtool pause setting implementation update the pause advertisement in the same way that phylib does, with the same caveats that are present there (as mentioned above w.r.t linkmode_set_pause()). 8. create a more accurate initial configuration for MACs, used when phy_start() is called or a SFP is detected. In particular, this ensures that the pause bits seen by MAC drivers in state->pause are accurate for SGMII. 9. finally, update the kerneldoc descriptions for mac_config() for the above changes. This series has been build-tested against net-next; the boot tested patches are in my "phy" branch against v5.5 plus the queued phylink changes that were merged for 5.6. The next series will introduce the ability for phylib drivers to provide hardware resolved pause enablement state. These patches can be found in my "phy" branch. ==================== Signed-off-by: -

Clarify the expected flow control settings operation in the phylink documentation for each negotiation mode. Signed-off-by:
Russell King <rmk+kernel@armlinux.org.uk> Reviewed-by:

Russell King authored
Improve the initial MAC configuration so we get a configuration which more represents the final operating mode, in particular with respect to the flow control settings. We do this by: 1) more fully initialising our phy state, so we can use this as the initial state for PHY based connections. 2) reading the fixed link state. 3) ensuring that in-band mode has sane pause settings for SGMII vs 802.3z negotiation modes. In all three cases, we ensure that state->link is false, just in case any MAC drivers have other ideas by mis-using this member, and we also take account of manual pause mode configuration at this point. This avoids MLO_PAUSE_AN being seen in mac_config() when operating in PHY, fixed mode or inband SGMII mode, thereby giving cleaner semantics to the pause flags. As a result of this, the pause flags now indicate in a mode-independent way what is required from a mac_config() implementation. Signed-off-by:
