rS301693: Multicast filters on DWC_GMAC_ALT_DESC type implementations use a different
Summary

Multicast filters are different between the two versions of dwc supported by the driver. This patch adds support for the second (DWC_GMAC_ALT_DESC mode) type of filters.

In addition, remove trailing FCS in receive path. dhclient complains:

ip length 334 disagrees with bytes received 338.

I wanted to use M_HASFCS here but if_ethersubr.c passes the mbuf to BPF before stripping FCS (so dhclient still complained).
