Subject: [net-next 16/17] igc: Fix wrong register name

From: Sasha Neftin <sasha.neftin@...el.com>

Accordance to the i225 datasheet this register address
used by Host Transmit Discarded Packet by MAC counter
and not by not applicable Carrier Extension Error counter.
This patch comes to fix this wrong definition.
