[PATCH net-next v4 07/12] ax88179_178a: Add AX179A/AX279 multicast configuration

[Birger Koblitz]

Add support for conditionally setting the ip_alignement flag
AX_RX_CTL_IPE in AX_RX_CTL and make sure that AX_RX_CTL_DROPCRCERR
is also set to be consistent with the initial configuration in
ax88179_reset()
