igb: mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
This patch fixes the following warning:
drivers/net/ethernet/intel/igb/e1000_82575.c: In function ‘igb_get_invariants_82575’:
drivers/net/ethernet/intel/igb/e1000_82575.c:636:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (igb_sgmii_uses_mdio_82575(hw)) {
^
drivers/net/ethernet/intel/igb/e1000_82575.c:642:2: note: here
case E1000_CTRL_EXT_LINK_MODE_PCIE_SERDES:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
