The igc driver first appeared in OpenBSD 7.1, and in NetBSD 10.0.

The igc driver was written by Intel Corporation and ported to OpenBSD by
Kevin Lo <kevlo@openbsd.org>. It was ported to NetBSD by
Kengo Nakahara <knakahara@NetBSD.org>,
Rin Okuyama <rin@NetBSD.org>, and
Masanobu SAITOH <msaitoh@NetBSD.org>.

The igc driver in NetBSD 10.0 is considered experimental. Some error handling paths are not fully implemented. It does not support hardware VLAN tagging and TSO at the moment.
