Subject[PATCH net-next] net: stmmac: Fix sparse warning
Date
The VID is converted to le16 so the variable must be __le16 type.

Reported-by: kbuild test robot <lkp@intel.com>
Fixes: c7ab0b8088d7 ("net: stmmac: Fallback to VLAN Perfect filtering if HASH is not available")
Signed-off-by: Jose Abreu <Jose.Abreu@synopsys.com>
