Subject: [PATCH net 0/3] mlxsw: Various fixes

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

This patch set contains various fixes for mlxsw.

Patch #1 ensures that only link modes that are supported by both the
device and the driver are advertised. When a link mode that is not
supported by the driver is negotiated by the device, it will be
presented as an unknown speed by ethtool, causing the bond driver to
wrongly assume that the link is down.

Patch #2 fixes a trivial memory leak upon module removal.

Patch #3 fixes a use-after-free that syzkaller was able to trigger once
on a slow emulator after a few months of fuzzing.
