75f2d3eac9 [netdrvr] sfc: Add phy_flash_cfg module parameter and implementation
The 10Xpress PHY supports flash upgrades through MDIO, but needs to be
put in upgrade mode at power-up.  This adds a module parameter and other
logic to support that.

b9b39b625c [netdrvr] sfc: Add TSO support
The SFC4000 controller does not have hardware support for TSO, and the
core GSO code incurs a high cost in allocating and freeing skbs.  This
TSO implementation uses lightweight packet header structures and is
substantially faster.
