The RPS bit is used to instruct the NIC to defer this update until after the packet has been transmitted on the wire (rather than merely read into the transmit FIFO). The driver currently sets RPS but not RS. Some e1000 models seem to interpret this as implying that the status byte should be updated; some don't. On the ones that don't, we never see any TX completions and so rapidly run out of TX buffers. Fix by setting the RS bit in the TX descriptor. (We don't care about when the packet reaches the wire, so don't bother setting the RPS bit.)

Avoid assigning the value to a variable, to inhibit a warning from gcc 4.6. Also fix a potential race condition in reset routines which clear interrupts before disabling them.

Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.
