Patch 1 also replaces the\n\">= X550 && <= x550em_a\" range check with three explicit mac.type\ncomparisons per Tony Nguyen's request.\n\nPatch 3 additionally handles the setup_fc() failure path that was\nleft unaddressed in the prior posting: fc_enable() is now skipped\nwhen setup_fc() fails so the MDD-triggering stale state is not\ncommitted to hardware.\n\nChanges in v2:\n - 1/6: Squash two patches; fix commit msg (\"200ms\" -> \"1s\"); three\n explicit mac.type == comparisons instead of range check.\n - 2/6: Add Fixes: tag; reroute from iwl-next to iwl-net.\n - 3/6: Add Fixes: tag; reroute to iwl-net; skip fc_enable() when\n setup_fc() fails to avoid committing stale FC state.\n - 4/6: Add Fixes: tag; reroute from iwl-next to iwl-net.\n - 5/6: Add proper [N/M] patch numbering.\n - 6/6: Reroute to iwl-net; swap to (expr >> ..) & MASK operand order.\n\n---\n\nAleksandr Loktionov (5):\n ixgbe: fix SWFW semaphore timeout for X550 family\n ixgbe: call ixgbe_setup_fc() before fc_enable() after NVM update\n ixgbe: fix cls_u32 nexthdr path returning success when no entry installed\n ixgbe: fix ITR value overflow in adaptive interrupt throttling\n ixgbe: fix integer overflow and wrong bit position in ixgbe_validate_rtr()\n\nPaul Greenwalt (1):\n ixgbe: add bounds check for debugfs register access\n\n drivers/net/ethernet/intel/ixgbe/ixgbe_debugfs.c | 4 ++--\n drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 18 ++++++++++++------\n drivers/net/ethernet/intel/ixgbe/ixgbe_x540.c | 8 ++++++++\n 3 files changed, 22 insertions(+), 8 deletions(-)"}
