Subject: [PATCH net 2/3] net: bcmgenet: use __be16 for htons(ETH_P_IP)

The 16-bit value that holds a short in network byte order should
be declared as a restricted big endian type to allow type checks
to succeed during assignment.

Fixes: 3e370952287c ("net: bcmgenet: add support for ethtool rxnfc flows")
