Subject: [PATCH net v3 2/2] ethtool: Add lanes parameter for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT

Lanes field is missing for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT
link mode and it causes a failure when trying to set
'speed 10000 lanes 1' on Spectrum-2 machines when autoneg is set to on.

Add the lanes parameter for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT
link mode.

Fixes: c8907043c6ac9 ("ethtool: Get link mode in use instead of speed and duplex parameters")
