sfxge: remove unused common code EFSYS_OPT_RX_HDR_SPLIT

The EFSYS_OPT_RX_HDR_SPLIT optional feature in the common code
implemented the Lookahead Split feature of Windows. This split
received packets at a preconfigured byte offset, and delivered
the header and payload portions to separate receive queues.

Now the common code interface has no callers, so remove it.

Note that this should not be confused with the Header Data Split
feature of Windows, which splits packets at a header boundary.

sfxge: [EF10] support RxQ scattering control

If, for example, a VF is configured to use a 1500 byte MTU, but the port
it is attached to is set to 9000 bytes, overlength frames can be received
by the VF. As Huntington scatters by default, these overlength packets
would be scattered across several descriptors, with all except the last
having the CONT bit set.

To avoid this, disable scatter when creating RXQs if the firmware
supports doing so, which all recent versions do. Then we only get
a single descriptor from an overlength frame. This will have the CONT
bit set to indicate it was truncated, so we can discard it.

prefast for error paths in common code functions.

sfxge: allow TX and RX queue limits to be changed

Before the common code had hard coded limits on the IDs RXQs and TXQs could
be created with which were suited for the Windows driver with VMQ, and so
would prevent queues with IDs greater than or equal to 259 (for TXQs) or 768
(for RXQs) from being created. This change allows the limits to be set in
efsys.h, so that all 1024 queues can be created during new manftest tests.
Also, the descriptor cache sizes were also hard coded to values suited to
the smaller queue counts, and so it was necessary to make them configurable
as well.

in all other event queues.

264772:
Check that port is started when MAC filter is set

The MAC filter set may be called without softc_lock held in the case of
SIOCADDMULTI and SIOCDELMULTI ioctls. The ioctl handler checks IFF_DRV_RUNNING
flag which implies port started, but it is not guaranteed to remain.
softc_lock shared lock can't be held in the case of these ioctls processing,
since it results in failure where kernel complains that non-sleepable
lock is held in sleeping thread.

Both problems are repeatable on LAG with LACP proto bring up.
