Subject: [PATCH net-next 0/3] ethtool: support for forward error correction mode setting on a link

From: Roopa Prabhu <roopa@...ulusnetworks.com>

Forward Error Correction (FEC) modes i.e Base-R
and Reed-Solomon modes are introduced in 25G/40G/100G standards
for providing good BER at high speeds. Various networking devices
which support 25G/40G/100G provides ability to manage supported FEC
modes and the lack of FEC encoding control and reporting today is a
source for itneroperability issues for many vendors.
FEC capability as well as specific FEC mode i.e. Base-R
or RS modes can be requested or advertised through bits D44:47 of base link
codeword.

This patch set intends to provide option under ethtool to manage and report
FEC encoding settings for networking devices as per IEEE 802.3 bj, bm and by
specs.
