Add kstat to cnmac(4)

This makes various receive and transmit event counters readable. This
additionally replaces the old, and somewhat unusual, way of updating
error counters in ifp.

Most of the hardware counters are 32 bits wide. Hence the code polls
them periodically and adds the values to 64-bit software counters.
The hardware counters are cleared when read.

Rename octeon_eth_* to cnmac_* for consistency with the driver's name.
This also makes the code a bit less noisy to read.

Assign each cnmac(4) port its own input work group, and assign
the interrupt processing of each work group to one of the available
CPUs. This enables some parallelism in the early stages of packet Rx.

Log RX errors only when the interface's debug flag is set.

While here, remove unused PIP error code aliases.

Drop a pointless link carrier check from the RX path.

Add support for jumbo frames.

Remove disabled jumbo frame checks. They will not be needed
for jumbo frame support.

Fill the packet data pool with standard mbuf clusters instead of
driver-specific memory blocks. This lets the cnmac(4) RX path run
without an mbuf ext_free callback.

Map ASX registers only if link control needs them.

ok mpi@

Make the TX path of cnmac(4) MP-safe and add some ifq oactive logic.

Feedback from dlg@, ok mpi@

sc_resume_ch is used nowhere.

Drop an unused workaround which does not even compile.

Remove the sc_soft_req_cnt field because the number of tx requests is
already tracked in sc_sendq. Replace the sc_flush logic with a simple
Fetch-and-Add store that avoids an unnecessary IOBDMA transaction.

ok uebayasi@

convert sc_sendq into an mbuf_list, and use ph_cookie rather than rcvif to
store the sgl address, allowing rcvif to be removed.

ok mpi@ dlg@ uebayasi@

Remove evcnt and %b format strings relying upon SEIL extensions. This gives
OCTEON_ETH_DEBUG kernels a chance to build. No functional change for regular
kernels.

Kill unused shutdown hook pointers.

ok miod@, deraadt@, tedu@

work out phy addresses before attaching cnmac and pass them to mii_attach
rather than hiding them in the mii read/write functions.
