sfc: support the ethtool ksettings API properly so that 25/50/100G works
Store and handle ethtool link mode masks within the driver instead of
just a single u32. However, quite a significant amount of existing code
wants to manipulate the masks directly, and thus now uses the first
unsigned long (i.e. mask[0]) as though it were a legacy u32 mask. This
is ok because all the bits that code is interested in are in the first
32 bits of the mask; but it might be a good idea to change them in
future to use the proper bitmap API.
