[PATCH 09/11] net: calxedaxgmac: remove some unused statistic counters

[Rob Herring]

From: Rob Herring <rob.herring@xxxxxxxxxxx>

rx_sa_filter_fail and tx_undeflow events are unused and impossible
to occur based on how the h/w is used. We never filter on source MAC
address and TX store and forward mode prevents underflow events.
