8d2e3a6161 nvethernet: fix MC filter corruption issue
Issue:
OSD Driver maintains a local MC address list to avoid the programming
old addresses again into HW when new MC address list passed from the
network stack.
Its observed MC address index for a specific address is different once a
MC address deleted from the list. Because of this new MC address which
is passed in new list is overwriting the old MC address.

Fix:
Program the entire list every time when network stack passes it instead
of maintaining local list at driver.

4612ee1b1e nvethernet: replace SUPPORTED_* to linkmode_*_bit() api.
Issue:
1) usuage of SUPPORTED_* in PHY driver for setting
the link mode parameters leading data corruption. So
replaced SUPPORTED_* with linkmode_*_bit in PHY driver.
2) Redundant code of setting Pause of PHY

Fix:
1) Change SUPPORTED_* to ETHTOOL_LINK_MODE_*_BIT for
consistent check between PHY and Ethernet driver for K5.10.
2) removed pause setting of PHY, since this is already
taken care in corresponding PHY drivers.

e6cde88eb8 nvethernet: move mdio_register to open
Issue: mdio bus is registered in probe and before exiting
probe ethernet clocks are disabled to save power. When SC7
is initiated then PHY framework invokes a PHY suspend which
triggers the PHY register write. Since clocks are not enabled
PHY register write is ignored and returned failure which
inturn prevented the entire system to enter into SC7

Fix: Move mdio bus registration to open so that PHY reads/writes
will not be invoked before bringing up the ethernet interface.
