Subject: [PATCH net 4/4] igc: Remove stale comment about Tx timestamping

From: Kurt Kanzenbach <kurt@...utronix.de>

The initial igc Tx timestamping implementation used only one register for
retrieving Tx timestamps. Commit 3ed247e78911 ("igc: Add support for
multiple in-flight TX timestamps") added support for utilizing all four of
them e.g., for multiple domain support. Remove the stale comment/FIXME.

Fixes: 3ed247e78911 ("igc: Add support for multiple in-flight TX timestamps")
