Marek Behún says: ====================- Add 5gbase-r PHY interface mode there is still some testing needed for Amethyst patches, so I have split the part adding support for 5gbase-r interface mode and am sending it alone. The first two patches are already reviewed. Changes since last patches (Amethyst v16): - added phylink 5gbase-r handler - added SFP support for 5gbase-r mode ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

The sfp_parse_support() function is setting 5000baseT_Full in some cases. Now that we have PHY_INTERFACE_MODE_5GBASER interface mode available, change sfp_select_interface() to return PHY_INTERFACE_MODE_5GBASER if 5000baseT_Full is set in the link mode mask. Signed-off-by:

The tg3 driver tried to communicate towards the PHY driver whether it wanted RGMII in-band signaling enabled or disabled however there is nothing that looks at those flags in drivers/net/phy/broadcom.c so this does do not anything. Suggested-by:

Especially the serdes calibration is large and is now placed in a new file 'mscc_serdes.c' which can act as a placeholder for future serdes configuration. v1 -> v2: Preserved reversed christmas tree Removed forward definitions Fixed build issues Changed net to net-next v2 -> v3: Added cover letter. Removed ena_clk_bypass from function call Created mscc_serdes.c and .h for serdes configuration Modified coma register config. ==================== Signed-off-by: -

The 'coma mode' (configurable through sw or hw) provides an optional feature that may be used to control when the PHYs become active. The typical usage is to synchronize the link-up time across all PHY instances. This patch releases coma mode if not done by hardware, otherwise the phys will not link-up.

The current IB serdes calibration algorithm (performed by the onboard 8051) has proven to be unstable for the VSC8514 QSGMII phy. A new algorithm has been developed based on 'Frequency-offset Jittered-Injection' or 'FoJi' method which solves all known issues. This patch disables the 8051 algorithm and replaces it with the new FoJi algorithm. The calibration is now performed in a new file (mscc_serdes.c), which can act as an placeholder for future serdes configurations. Fixes: e4f9ba64 ("net: phy: mscc: add support for VSC8514 PHY.")

At Power-On Reset, transients may cause the LCPLL to lock onto a clock that is momentarily unstable. This is normally seen in QSGMII setups where the higher speed 6G SerDes is being used. This patch adds an initial LCPLL Reset to the PHY (first instance) to avoid this issue. Fixes: e4f9ba64 ("net: phy: mscc: add support for VSC8514 PHY.") Signed-off-by:

Vladimir Oltean says: ==================== Fix buggy brport flags offload for SJA1105 DSA I am resending this series because the title and the patches were mixed up and these patches were lost. This series' cover letter was used as the merge commit for the unrelated "Fixing build breakage after "Merge branch 'Propagate-extack-for-switchdev-LANs-from-DSA'"" series, as can be seen below: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=ca04422afd6998611a81d0ea1b61d5a5f4923f84 while the actual patches from the "Fix buggy brport flags offload for SJA1105 DSA" series were marked as superseded and not applied: https://patchwork.kernel.org/project/netdevbpf/cover/20210214155704.1784220-1-olteanv@gmail.com/ which they should have. I know with so many bugs I introduced it's hard to keep track, I'm sorry. Original series description: While testing software bridging on sja1105, I discovered that I managed to introduce two bugs in a single patch submitted recently to net-next. ==================== Signed-off-by:

Vladimir Oltean authored
Quite embarrasingly, I managed to fool myself into thinking that the flooding domain of sja1105 source ports is restricted by the forwarding domain, which it isn't. Frames which match an FDB entry are forwarded towards that entry's DESTPORTS restricted by REACH_PORT[SRC_PORT], while frames that don't match any FDB entry are forwarded towards FL_DOMAIN[SRC_PORT] or BC_DOMAIN[SRC_PORT]. This means we can't get away with doing the simple thing, and we must manage the flooding domain ourselves such that it is restricted by the forwarding domain. This new function must be called from the .port_bridge_join and .port_bridge_leave methods too, not just from .port_bridge_flags as we did before.

Vladimir Oltean authored
Due to a mistake, the driver always sets the address learning flag to the previously stored value, and not to the currently configured one. The bug is visible only in standalone ports mode, because when the port is bridged, the issue is masked by .port_stp_state_set which overwrites the address learning state to the proper value.

Some internal PHY's have their events like link change reported by the MAC interrupt. We have PHY_IGNORE_INTERRUPT to deal with this scenario. I'm not too happy with this name. We don't ignore interrupts, typically there is no interrupt exposed at a PHY level. So let's rename it to PHY_MAC_INTERRUPT. This is in line with phy_mac_interrupt(), which is called from the MAC interrupt handler to handle PHY events. Signed-off-by:

We have a number of unused flags defined today and since we are scarce on space and may need to introduce new flags in the future remove and shift every existing flag down into a contiguous assignment. PHY_BCM_FLAGS_MODE_1000BX was only used internally for the BCM54616S PHY, so we allocate a driver private structure instead to store that flag instead of canibalizing one from phydev->dev_flags for that purpose.

Hardware comes up with default max frame size set to 1518. When using it with switch it results in actual Ethernet MTU 1492: 1518 - 14 (Ethernet header) - 4 (Broadcom's tag) - 4 (802.1q) - 4 (FCS) Above means hardware in its default state can't handle standard Ethernet traffic (MTU 1500). Define maximum possible Ethernet overhead and always set MAC max frame length accordingly. This change fixes handling Ethernet frames of length 1506 - 1514. Signed-off-by:

test_global_func4 fails on s390 as reported by Yauheni in [1]. The immediate problem is that the zext code includes the instruction, whose result needs to be zero-extended, into the zero-extension patchlet, and if this instruction happens to be a branch, then its delta is not adjusted. As a result, the verifier rejects the program later. However, according to [2], as far as the verifier's algorithm is concerned and as specified by the insn_no_def() function, branching insns do not define anything. This includes call insns, even though one might argue that they define %r0. This means that the real problem is that zero extension kicks in at all. This happens because clear_caller_saved_regs() sets BPF_REG_0's subreg_def after global function calls. This can be fixed in many ways; this patch mimics what helper function call handling already does.

The sja1105 driver has a limitation, extensively described under Documentation/networking/dsa/sja1105.rst and Documentation/networking/devlink/sja1105.rst, which says that when the ports are under a bridge with vlan_filtering=1, traffic to and from the network stack is not possible, unless the driver-specific best_effort_vlan_filtering devlink parameter is enabled. For users, this creates a 'wtf' moment. They need to go to the documentation and find about the existence of this property, then maybe install devlink and set it to true. Having best_effort_vlan_filtering enabled by the kernel by default delays that 'wtf' moment (maybe up to the point that it never even happens). The user doesn't need to care that the driver supports addressing the ports individually by retagging VLAN IDs until he/she needs to use more than 32 VLAN IDs (since there can be at most 32 retagging rules). Only then do they need to think whether they need the full VLAN table, at the expense of no individual port addressing, or not. But the odds that an sja1105 user will need more than 32 VLANs terminated by the CPU is probably low. And, if we were to follow the principle that more advanced use cases should require more advanced preparation steps, then it makes more sense for ping to 'just work' while CPU termination of > 32 VLAN IDs to require a bit more forethought and possibly a driver-specific devlink param. So we should be able to safely change the default here, and make this driver act just a little bit more sanely out of the box. Signed-off-by:
