net: stmmac: move check for hardware checksum supported

Browse source

Add a check in .ndo_features_check() to indicate whether hardware
checksum can be performed on the skbuff. Where hardware checksum is
not supported - either because the channel does not support Tx COE
or the skb isn't suitable (stmmac uses a tighter test than
can_checksum_protocol()) we also need to disable TSO, which will be
done by harmonize_features() in net/core/dev.c

This fixes a bug where a channel which has COE disabled may still
receive TSO skbuffs.
