[ Upstream commit bd74d4ea29cc3c0520d9af109bb7a7c769325746 ]
This patch adds support to fetch fec stats from PHY. The stats are
put in the shared data struct fwdata. A PHY driver indicates
that it has FEC stats by setting the flag fwdata.phy.misc.has_fec_stats
Besides CGX_CMD_GET_PHY_FEC_STATS, also add CGX_CMD_PRBS and
CGX_CMD_DISPLAY_EYE to enum cgx_cmd_id so that Linux's enum list is in sync
with firmware's enum list.

CGX block supports forward error correction modes baseR
and RS. This patch adds support to set encoding mode
and to read corrected/uncorrected block counters
Adds new mailbox handlers set_fec to configure encoding modes
and fec_stats to read counters and also increase mbox timeout
to accomdate firmware command response timeout.
Along with new CGX_CMD_SET_FEC command add other commands to
sync with kernel enum list with firmware.

The Octeontx2 MAC block (CGX) has separate data paths (SMU and GMP) for
different speeds, allowing for efficient data transfer.
The previous patch which added pause frame configuration has a bug due
to which pause frame feature is not working in GMP mode.
This patch fixes the issue by configurating appropriate registers.

Use wake_up API instead of wake_up_interruptible, since
wait_event_timeout API is used for waiting on command completion.
