Add basic WOL support for MCP ethernet controllers. It seems the
controller does not perform automatic switching from 1000Mbps link
to 10/100Mbps link when WOL is activated. Implement establishing
10/100Mps link with auto-negotiation in driver. Link status change
handler was modified to remove taskqueue based approach since driver
now needs synchronous handling for link establishment.

Nuke local jumbo allocator and switch to use of UMA backed page
allocator for jumbo frame. Also remove unneeded jlist lock which
is no longer required to protect jumbo buffers.
With these changes jumbo frame performance of nfe(4) was slightly
increased and users should not encounter jumbo buffer allocation
failure anymore.

Don't fail on device attach if jumbo frame support was unsuccessful.
Because nfe(4) hardware doesn't support SG on Rx path, supporting
jumbo frame requires very large contiguous kernel memory(i.e. several
mega bytes). In case of lack of contiguous kernel memory that
allocation request may always fail. However nfe(4) can operate on normal
sized MTU frames, so go ahead and just disable jumbo frame support.
While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable
jumbo frame support.
In nfe_poll, make sure to invoke correct Rx handler.

Special thanks to Shigeaki Tagashira, the original porter of nfe(4),
who submitted lots of patches, performed uncountable number of
regression tests and maintained nfe(4) for a long time. Without his
enthusiastic help and support I could never have completed this
overhauling task.

The only weak point of nfe(4) compared to nve(4) is instability of
manual half-duplex media selection on certain hardwares(auto sensing
media type should work for all cases, though). This was a long
standing bug of nfe(4) and I still have no idea why it doesn't work
on some hardwares.
