1532ecea1d e1000: drop dead pcie code from e1000
this patch is the first in a series of clean up patches for e1000 to drop
unused code, and update the driver to kernel spec, and then, to update the
driver to have all available bug fixes.

Call it the e1000 weight loss plan.

b7cb8c2c82 e1000: fix flow control thresholds
when testing the jumbo frames with pages patch, the stats would
show rx_missed errors (dropped packets) even when connected to a
link partner with flow control enabled.

this indicates that for this MTU (9000) the flow control
thresholds are not adjusting correctly.

In fact, before this change, the FCRTH (xoff threshold) is 36864
when the fifo size is only 40000, with 9000 byte MTU.

fix it so that we at least have room for one frame after we send
the xoff.
