When lower device like bonding slave, team/bridge port, etc changes its state, it is useful for others to notice this change. Currently this is implemented specificly for bonding as NETDEV_BONDING_INFO notifier. This patch aims to replace this specific usage and make this more generic to be used for all upper-lower devices. Introduce NETDEV_CHANGELOWERSTATE netdev notifier type and netdev_lower_state_changed() helper. Signed-off-by:

Sometimes the drivers and other code would find it handy to know some internal information about upper device being changed. So allow upper-code to pass information down to notifier listeners during linking. Signed-off-by:

Since CHANGEUPPER can now fail, add support for it in the newly introduced netdev notifier error injection infrastructure. Signed-off-by:

Ido Schimmel authored
switchdev drivers reflect the newly requested topology to hardware when CHANGEUPPER is received, after software links were already formed. However, the operation can fail and user will not be notified, as the return value of the notifier is not checked. Add this check and rollback software links if necessary. Signed-off-by:

Commit 7fd89545 ("i40e: remove BUG_ON from feature string building") added defective output when I40E_FLAG_VEB_MODE_ENABLED was set in function i40e_print_features. Fix it. Miscellanea: - Remove unnecessary string variable - Add space before not after fixed strings - Use kmalloc not kzalloc - Don't initialize i to 0, use result of first snprintf Reported-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-12-03 This series contains updates to ixgbe and ixgbevf only. Mark cleans up ixgbe_init_phy_ops_x550em, since this was designed to initialize function pointers only and moves the KR PHY reset to the ixgbe_setup_internal_phy_t_x550em which was designed to detect which mode the PHY operates in and set it up. Added the new thermal alarm type support used with newer X550EM_x devices. Fixed both ixgbe and ixgbevf to use a private work queue to avoid hangs, which would possibly occur when creating and destroying many VFS repeatedly. Updated ixgbe PTP implementation to accommodate X550EM_x devices, which handle clocking differently. Fixed specification violations in the datasheet, which was reported by Dan Streetman. Fixed ixgbe to check for and handle IPv6 extended headers so that Tx checksum offload can be done, which was reported by Tom Herbert. Fixed ixgbe link issue for some systems with X540 or X550 by only inhibiting the turning PHY power off when manageability is present. Alex Duyck refactors the MAC address configuration code, which in turns fixes an issue where once 63 entries had been used, you could no longer add additional filters. Updated ixgbe to use __dev_uc_sync which also resolved an issue in which you could not remove an FDB address without having to reset the port. Updated the ixgbe driver to make use of all the free RAR entries for FDB use if needed. v2: updated patch 13 to "Alex Duyck Approved" version, in the original submission, I had grabbed a previous version of the patch and did not catch it was superseded by a later version ==================== Signed-off-by: -

Instead of inhibiting PHY power control when manageability is present, only inhibit turning PHY power off when manageability is present. Consequently, PHY power will always be turned on when requested. Without this patch, some systems with X540 or X550 devices in some conditions will never get link. Signed-off-by:

The ixgbe driver was violating the specification in the datasheet by not waiting 1ms before checking for the reset bit clearing. This is called out for devices supported by ixgbe, so implement the required delay. Reported-by:

The X550EM_x devices handle clocking differently, so update the PTP implementation to accommodate them. This involves significant changes to ixgbe's PTP code to accommodate the new range of behaviors including things like non-power-of-2 clock wrapping. Signed-off-by:

This change makes it so that we allow the PF to make use of all free RAR entries for FDB use if needed. Previously the code limited us to 16 unicast entries, however this was shared between MACVLAN which wasn't limited and the FDB code which was. So instead of treating the FDB code as a second class citizen I have updated it so that it has access to just as many entries as the MACVLAN filters. Signed-off-by:

This change replaces the ixgbe_write_uc_addr_list call in ixgbe_set_rx_mode with a call to __dev_uc_sync instead. This works much better with the MAC addr list code that was already in place and solves an issue in which you couldn't remove an FDB address without having to reset the port. Signed-off-by:

In the process of tracking down a memory leak when adding/removing FDB entries I had to go through the MAC address configuration code for ixgbe. In the process of doing so I found a number of issues that impacted readability and performance. This change updates the code in general to clean it up so it becomes clear what each step is doing. From what I can tell there a couple of bugs cleaned up in this code. First is the fact that the MAC addresses were being double counted for the PF. As a result once entries up to 63 had been used you could no longer add additional filters. A simple test case for this: for i in `seq 0 96` do ip link add link ens8 name mv$i type macvlan ip link set dev mv$i up done Test script: ethregs -s 0:8.0 | grep -e "RAH" | grep 8000....$ When things are working correctly RAL/H registers 1 - 97 will be consumed. In the failing case it will stop at 63 and prevent any further filters from being added. Signed-off-by: -

This patch removes KR PHY reset from ixgbe_init_phy_ops_x550em, since this function is meant to initialize function pointers for the detected PHY type. Internal PHY reset was moved to ixgbe_setup_internal_phy_t_x550em which will now detect which mode the internal PHY operates in and set it up as required. Signed-off-by:

If tcp_send_ack() can not allocate skb, we properly handle this and setup a timer to try later. Use __GFP_NOWARN to avoid polluting syslog in the case host is under memory pressure, so that pertinent messages are not lost under a flood of useless information. sk_gfp_atomic() can use its gfp_mask argument (all callers currently were using GFP_ATOMIC before this patch) We rename sk_gfp_atomic() to sk_gfp_mask() to clearly express this function now takes into account its second argument (gfp_mask) Note that when tcp_transmit_skb() is called with clone_it set to false, we do not attempt memory allocations, so can pass a 0 gfp_mask, which most compilers can emit faster than a non zero or constant value.

Merge branch 'hv_netvsc-less-headroom' K. Y. Srinivasan says: ==================== hv_netvsc: Eliminate the additional head room In an attempt to avoid having to allocate memory on the send path, the netvsc driver was requesting additional head room so that both rndis header and the netvsc packet (the state that had to persist) could be placed in the skb. Since the amount of head room requested was exceeding the default head room as set in LL_MAX_HEADER, we were forcing a reallocation of skb. With this patch-set, I have reduced the size of the netvsc packet to less than 20 bytes and with this reduction we don't need to ask for any additional headroom. We place the rndis header in the skb head room and we place the netvsc packet in control buffer area in the skb. V2: - Addressed review comments: - Eliminated more fields from netvsc packet structure. V3: - Fixed a typo in patch: hv_netvsc: Don't ask for additional head room in the skb. ==================== Signed-off-by: -
