Subject: [PATCH net 0/6] mlxsw fixes

From: Ido Schimmel <idosch@...lanox.com>

This patch set contains various fixes for mlxsw.

Patches #1-#2 fix two trap related issues introduced in previous cycle.

Patches #3-#5 fix rare use-after-frees discovered by syzkaller. After
over a week of fuzzing with the fixes, the bugs did not reproduce.

Patch #6 from Amit fixes an issue in the ethtool selftest that was
recently discovered after running the test on a new platform that
supports only 1Gbps and 10Gbps speeds.

Amit Cohen (1):
  selftests: ethtool: Fix test when only two speeds are supported

Ido Schimmel (5):
  mlxsw: spectrum_router: Allow programming link-local host routes
  mlxsw: spectrum: Use different trap group for externally routed
    packets
  mlxsw: core: Increase scope of RCU read-side critical section
  mlxsw: core: Free EMAD transactions using kfree_rcu()
  mlxsw: spectrum_router: Fix use-after-free in router init / de-init
