This commit is a little bit misleading.

/* Since changing of pause setting, with pause auto negotiation off,
   doesn't trigger any link change event, the driver needs to update
   the current MAC pause upon successful return of the phy_cfg command
   */

The pause auto negotiation off is important here.

The code is not the easiest to read because it mixes up PHY and MAC
configuration.

1) If autoneg and autoneg pause is used, you only configure the PHY.
When autoneg completes, you then configure the MAC with the results of
the negotiation.

2) If autoneg is used, but not pause autoneg, you can optionally
remove pause from being advertised by the PHY, but you need to
immediately configure the MAC.

3) If autoneg is off, you you need to immediately configure the MAC.

Thanks for the review, Andrew.

I will update the comment in the next spin and refactor bnge_hwrm_set_pause()
to improve readability and add more comments for better understanding.

Thanks,
