ixgbe: Refactor common code between 82598 & 82599 to accommodate new hardware
Some of the following MAC functions are moved from 82598 & 82599 specific hardware files to common.[ch] to accommodate new silicon changes. Also fixed some white space issues * get_san_mac_addr, check_link, set_vmdq, clear_vmdq, clear_vfta, * set_vfta, fc_enable, init_uta_tables Signed-off-by: Mallikarjuna R Chilakala <mallikarjuna.chilakala@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.
