Change semantics of network API so that packet-absorbing calls *always*
...
take ownership of the packet, rather than doing so only if they return
success. This breaks semantic compatibility with Linux's
hard_start_xmit() method, but means that we don't have to worry so much
about error cases.
Split mechanism of processing received packets (net_rx_process()) out
from policy (net_step()), preparatory to putting net_step() in a separate
object.

Header rearrangement.
...
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/. Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.

Network API now allows for multiple network devices (although the

Link-layer and network-layer protocols are cleanly separated from each
