Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-05-07 This series contains updates to igb only. Toshiaki provides two fixes for igb, first fixes an issue when changing the number of rings by ethtool which causes oops because of uninitialized pointers. The second fix resolves a typo where tx_ring was used instead of the desired rx_ring. ====================
