eee_get_cur assumes that the output data is already zeroed. It can
read-modify-write the advertised field:

              if (ipcnfg & E1000_IPCNFG_EEE_100M_AN)
2594			edata->advertised |= ADVERTISED_100baseT_Full;

This is ok for the normal ethtool eee_get call, which always
zeroes the input data before.

But eee_set_cur also calls eee_get_cur and it did not zero the input
field. Later on it then compares agsinst the field, which can contain partial
stack garbage.

Zero the input field in eee_set_cur() too.

This patch renames the LL_EXTENDED_STATS and some of the functions required to
implement busy polling in the ixgbe driver, in order to remove the marketing
"low latency" blurb which hides what the code actually does.

This furthers work which was requested by Linus Torvalds when the initial busy
poll code was included in the kernel. The code in the ixgbe driver itself was
never properly renamed to reflect the change to busy polling as the title.
