We utilize inline functions from the PHY library, make sure that we do include phy.h in brcmphy.h in order for the code including brcmphy.h not to have to resolve this inclusion dependency. Fixes: 70531479 ("net: phy: broadcom: move shadow 0x1C register accessors to brcmphy.h") Signed-off-by:

dctcp_alpha can be read by from dctcp_get_info() without synchro, so use WRITE_ONCE() to prevent compiler from using dctcp_alpha as a temporary variable. Also, playing with small dctcp_shift_g (like 1), can expose an overflow with 32bit values shifted 9 times before divide. Use an u64 field to avoid this problem, and perform the divide only if acked_bytes_ecn is not zero. Signed-off-by:

Merge tag 'mac80211-next-for-davem-2015-06-10' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next Johannes Berg says: ==================== For this round we mostly have fixes: * mesh fixes from Alexis Green and Chun-Yeow Yeoh, * a documentation fix from Jakub Kicinski, * a missing channel release (from Michal Kazior), * a fix for a signal strength reporting bug (from Sara Sharon), * handle deauth while associating (myself), * don't report mangled TX SKB back to userspace for status (myself), * handle aggregation session timeouts properly in fast-xmit (myself) However, there are also a few cleanups and one big change that affects all drivers (and that required me to pull in your tree) to change the mac80211 HW flags to use an unsigned long bitmap so that we can extend them more easily - we're running out of flags even with a cleanup to remove the two unused ones. ==================== Signed-off-by:

SCM_SECURITY was originally only implemented for datagram sockets, not for stream sockets. However, SCM_CREDENTIALS is supported on Unix stream sockets. For consistency, implement Unix stream support for SCM_SECURITY as well. Also clean up the existing code and get rid of the superfluous UNIXSID macro. Motivated by https://bugzilla.redhat.com/show_bug.cgi?id=1224211, where systemd was using SCM_CREDENTIALS and assumed wrongly that SCM_SECURITY was also supported on Unix stream sockets.

Use the timer API function setup_timer instead of structure field assignments to initialize a timer. A simplified version of the Coccinelle semantic patch that performs this transformation is as follows: @change@ expression e1, e2, a; @@ -init_timer(&e1); +setup_timer(&e1, a, 0UL); ... when != a = e2 -e1.function = a; Signed-off-by:

The series adds additional support for x550 support, such as WoL and auto-negotiation of flow control. Adds new PHY support (external PHY) for x550, as well as the new methods/functions needed to support the new PHY's. Fixed a bug found in code inspection, where a check was missed when clearing counters for x550. Also fixed the init code flow for copper x550 devices. ==================== Signed-off-by: -

Before this patch the user-specified bridge port was ignored when deleting an fdb entry and thus one could delete an entry that belonged to any port. Example (eth0 and eth1 are br0 ports): bridge fdb add 00:11:22:33:44:55 dev eth0 master bridge fdb del 00:11:22:33:44:55 dev eth1 master (succeeds) after the patch: bridge fdb add 00:11:22:33:44:55 dev eth0 master bridge fdb del 00:11:22:33:44:55 dev eth1 master RTNETLINK answers: No such file or directory Based on a patch by Wilson Kok.

As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

This patch fixes a bug in hwmp_preq_frame_process where the wrong metric can be used when forwarding a PREQ. This happens because the code uses the same metric variable to record the value of the metric to the source of the PREQ and the value of the metric to the target of the PREQ. This comes into play when both reply and forward are set which happens when IEEE80211_PREQ_PROACTIVE_PREP_FLAG is set and when MP_F_DO | MP_F_RF is set. The original code had a special case to handle the first case but not the second. The patch uses distinct variables for the two metrics which makes the code flow much clearer and removes the need to restore the original value of metric when forwarding. Signed-off-by:

We need to call the set_lan_id before accessing I2C and this wasn't being done so this patch corrects that. Likewise we do the same for QSFP just to be consistent. In the X550 case this is even more important as with out it the mux is not controlled properly. Signed-off-by:

This patch adds ixgbe_check_link_t_X550em for checking copper PHY link. We check that both the MAC and external PHY have link. This is to avoid a false link up between the internal and external PHY when the external PHY doesn't have link. Signed-off-by:

Reviewing the X550 copper init flow with the Si team resulted in a new simplified flow. We no longer wait for the PHY FW initialization complete bit to be set as this bit is only set once by the PHY at power on and then cleared on the first read. So only the first instance of running SW (or possibly MAC FW) needs to initialize the PHY. The PHY initialization has been simplified and now only requires that the PHY FW be un-stalled low-power mode or enabled the transceiver Signed-off-by:

Add checks for systems that don't have SFP's to avoid incorrectly acting on interrupts that are falsely interpreted as SFP events. We do this by updating the ixgbe_is_sfp to be aware of the new X550 devices. This also includes a modified check generating the EICR mask to be more forward-looking. Signed-off-by:

This patch adds x550 external PHY interrupt and forced 1G/10G support. This included enabling and handling LSC and thermal sensor interrupt. ixgbe_handle_lasi() has been added for handling the interrupts received over SDP0 from the external 10baseT PHY. ixgbe_enable_lasi_ext_t_x550em and ixgbe_get_lasi_ext_t_x550em have been added to X550em to enable mask and check interrupt flags for the external PHY. Forced 1G/10G link speed is handled via ixgbe_mac_link_t_X550em. ixgbe_seupt_mac_link_t_X550em sets up the internal PHY and external PHY to either iXFI (10G) or KX (1G) based on the user selected auto advertised link speed setting. Then sets up the external PHY auto advertised link speed. Signed-off-by:

Some of the register addresses and format where unfortunately changed between MAC types. To get around this we add a const u32 *mvals pointer to the ixgbe_hw struct to point to an array of mac-type-dependent values. These can include register offsets, masks, whatever can be in a u32. When the ixgbe_hw struct is initialized, a pointer to the appropriate array must be set. Signed-off-by:

In mesh mode there is a race between establishing links and processing rates and capabilities in beacons. This is very noticeable with slow beacons (e.g. beacon intervals of 1s) and manifested for us as stations using minstrel when minstrel_ht should be used. Fixed by changing mesh_sta_info_init so that it always checks rates and such if it has not already done so. Signed-off-by:

Channels in 2.4GHz band overlap, this means that if we send a probe request on channel 1 and then move to channel 2, we will hear the probe response on channel 2. In this case, the RSSI will be lower than if we had heard it on the channel on which it was sent (1 in this case). The scan result ignores those invalid values and the station last signal should not be updated as well. In case the scan determines the signal to be invalid turn on the flag so the station last signal will not be updated with the value and thus user space probing for NL80211_STA_INFO_SIGNAL and NL80211_STA_INFO_SIGNAL_AVG will not get this invalid RSSI value.
