sfc: Implement auto-negotiation
Add infrastructure for auto-negotiation of speed, duplex and flow control. When using 10Xpress, auto-negotiate flow control. While we're at it, clean up the code to warn when partner is not 10GBASE-T capable. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
