Added support for application management interface. There are two types of commands supported:
1. Firmware IOCTLs: These ioctls are meant for firmware
consumption. Driver acts as a transport for these.
2. Driver only IOCTLs: These ioctls are meant for driver
consumption. Driver will serve these ioctls without sending them down
to firmware.

While here, clean up magic numbers.
The memset(,0,) (and M_ZERO!) can just be removed; the bit_alloc() API already
zeros the allocation.
No functional change.

New Stratus bnxt devices require support for short HWRM commands for VFs
to function. Enable their use, but only use them if it's both supported
and required... prefer the long HWRM commands when possible.

The firmware is always in little endian, use htole*() for all request fields
larger than one byte.

1) Choose correct Firmware options for HW LRO for best performance
2) Delete TBD and other comments which are not required.
3) Added sysctl interface to enable / disable / modify different factors
of HW LRO.
4) Disabled HW LRO by default to avoid issues with packet forwarding
This allows much better control over the LRO configuration via sysctls, and
uses much better defaults. Hardware LRO can now be enabled/disabled
independantly from the software LRO, and the tuning parameters are exposed.
manpage updates coming soon.

- Use HWRM_FUNC_VF_CFG instead of HWRM_FUNC_CFG on VFs
- Fix NPAR/VF detection
- Clean up flag definitions
- Don't allow WoL on VFs
Although the bnxt driver doesn't support SR-IOV so can create VFs yet,
the PF could be running Linux or ESCi with a VF passed through to a
FreeBSD guest. This fixes the driver for that use case.

iflib - reset fl-ifl_fragidx to 0 on iflib_fl_bufs_free(). This caused the
panic in em/igb when adding it to a bridge device.
iflib - Handle out of order packet delivery from hardware in support of LRO
Out of order updates to rxd's is fixed in r315217. However, it is not
completely fixed. While refilling the buffers, iflib is not considering
the out of order descriptors. Hence, it is refilling sequentially.
"idx" variable in _iflib_fl_refill routine is incremented sequentially.
By doing refilling sequentially, it will override the SGEs that
are *IN USE* by other connections. Fix is to maintain a bitmap of
rx descriptors and differentiate the used one with unused one and
refill only at the unused indices. This patch also fixes a
few bugs in bnxt, related to the same feature.
