Merge branch 'mlxsw-fixes'
Jiri Pirko says: ==================== mlxsw: IPv4 UC router fixes Ido says: Patches 1-3 fix a long standing problem in the driver's init sequence, which manifests itself quite often when routing daemons try to configure an IP address on registered netdevs that don't yet have an associated vPort. Patches 4-9 add missing packet traps for the router to work properly and also fix ordering issue following the recent changes to the driver's init sequence. The last patch isn't related to the router, but fixes a general problem in which under certain conditions packets aren't trapped to CPU. v1->v2: - Change order of patch 7 - Add patch 6 following Ilan's comment - Add patchset name and cover letter ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
