[PATCH net-next] net: stmmac: Fix sparse warning

From: Jose Abreu
Date: Mon Oct 07 2019 - 09:16:19 EST


The VID is converted to le16 so the variable must be __le16 type.

Reported-by: kbuild test robot <lkp@xxxxxxxxx>
Fixes: c7ab0b8088d7 ("net: stmmac: Fallback to VLAN Perfect filtering if HASH is not available")
