====================
net: stmmac: Improve mcast/ucast filter for snps

This patch series adds Synopsys specific bindings for the Synopsys EMAC
filter characteristics since those are implementation dependent. The
multicast and unicast filtering code was improved to handle different
configuration variations based on device tree settings.

I verified the operation of the multicast and unicast filters through
Synopsys support as requested during the V1 review, and tested the GMAC
configuration on an Altera Cyclone 5 SOC (which supports 256 multicast
bins and 128 Unicast addresses). The 10/100 variant of this driver
modification was not tested, although it was compile tested. I shared
the email thread results of the investigation through Synopsys with the
stmmac maintainer.

V4: Remove patch from series that addressed a sparse issue from a
    down rev'd version of sparse that does not show up in the
    latest version of sparse.
V3: Break up the patch into interface and functional change patches
    per review comments
V2: Confirm with Synopsys methods to determine number of Multicast bins
    and Unicast address filter entries per first round review comments.
