This patch adds the ethtool callbacks necessary to change the rss
indirection table from userspace. Should the number of interrupts
change (e.g. across a close / open call, or through a reset) and
any one of the indirection table values fall out-of-range, the driver
will reset the indirection table to a default layout.
[Integrated many suggestions made by Ben Hutchings.]
Changes since v3
* Removed TG3_FLAG_SUPPORT_MSIX checks at the start of
tg3_get_rxfh_indir() and tg3_set_rxfh_indir().
