ixgbe: Add SAN MAC address to the RAR, return the address to DCB
After acquiring the SAN MAC address from the EEPROM, we need to program it into one of the RARs. Also, DCB will use this MAC address to run DCBX commands, so it doesn't have to play musical MAC addresses when things like bonding enter the picture. So we need to return the MAC address through the netlink interface to userspace. This also moves the init_rx_addrs() call out of start_hw() and into reset_hw(). We shouldn't try to read any of the RAR information before initializing our internal accounting of the RAR table, which was what was happening.
