net: wangxun: don't advertise IFF_SUPP_NOFCS
Like commit a24162f18825("i40e: don't advertise IFF_SUPP_NOFCS"),
ngbe and txgbe also advertises IFF_SUPP_NOFCS and allowing users
to use the SO_NOFCS socket option. But the driver does not check
skb->no_fcs, so this option is silently ignored.
With this change, send() fails with -EPROTONOSUPPORT when AF_PACKET
socket is set SO_NOFCS option.
