Merge branch 'bond-3ad-200g-400g'

Nikolay Aleksandrov says:

====================
bonding: 3ad: support for 200G/400G ports and more verbose warning
xk
We'd like to have proper 200G and 400G support with 3ad bond mode, so we
need to add new definitions for them in order to have separate oper keys,
aggregated bandwidth and proper operation (patches 01 and 02). In
patch 03 Ido changes the code to use pr_err_once instead of
pr_warn_once which would help future detection of unsupported speeds.

v2: patch 03: use pr_err_once instead of WARN_ONCE
====================
