1. correct the initialization of RDT when there is an ixgbe_init()
while a netmap client is active. This code was previously
in ixgbe_initialize_receive_units() but RDT is overwritten
shortly afterwards in ixgbe_init_locked()
2. add code (not active yet) to disable CRCSTRIP while in netmap mode.
From all evidence i could gather, it seems that when the 82599 has to
write a data block that is not a full cache line, it first reads
the line (64 bytes) and then writes back the updated version.
This hurts reception of min-sized frames, which are only 60 bytes
if the CRC is stripped: i could never get above 11Mpps
(received from one queue) with CRCSTRIP enabled, whyle 64+4-byte
packets reach 14.2 Mpps (the theoretical maximum).
Leaving the CRC in gets us 14.88Mpps for 60+4 byte frames,
(and penalizes 64+4). The min-size case is important not just because
it looks good in benchmarks, but also because this is the size
of pure acks.
Note we cannot leave CRCSTRIP on by default because it is
incompatible with some other features (LRO etc.)
of HDA bus. Handle that from two directions:
- Add support for "striping" (using several SDO lines), if supported.
- Account HDA bus utilization and return error on new stream allocation
attempt if remaining bandwidth is unsifficient.
Most of HDA controllers have one SDO line with 46Mbps output bandwidth.
NVIDIA GF210 has 2 lines - 92Mbps. NVIDIA GF520 has 4 lines - 184Mbps!

- Enable and handle unsolicited responses from digital display pins,
reporting connection and EDID-Like Data (ELD) validity status changes.
- Fetch ELD data, describing connected digital display device audio
capabilities. These data not really used at the moment (user is not
denied to use audio formats not supported by the device), only printed to
verbose logs. But they are useful for debugging. The fact that ELD was
received tells that HDMI link was established and video driver enabled
HDMI audio passthrough. Some old chips may not return ELD, so lack of it
is not necessary a problem.
- Add some more points to CODEC configuration sequence:
- For converter widgets, supporting more then two channels (HDMI/DP
converter widgets support 8), set number of channels to handle.
- For digital display pins (HDMI/DP) fill audio infoframe, reporting
connected device about number of channels and speakers allocation.
- For digital display pins (HDMI/DP) set mapping between channels seen
by software and channels transferred via HDMI/DisplayPort.
- Allow more audio formats, not used for analog connections because of
stereo pairs orientation, but easily applicable to HDMI/DisplayPort: 2.1,
3.0, 3.1, 4.1, 5.0, 6.0, 6.1, 7.0. That list may be filtered later using
info from ELD.
- Disable MSI interrupts for NVIDIA HDA controllers before GT520.

6.0, 6.1, 7.0 and 7.1 PCM formats are not working for me, but I think
it is because of receiver age.

the LDADD/DPADD to lose the -lpam, and causing openpam_dynamic() to fail
due to "openpam_get_options" being undefined.
This would cause obscure console log messages like:
openpam_dynamic(): No error: 0
openpam_load_module(): no pam_unix.so found
and other helpful messages which are no help in diagnosing the problem.
Fortunately this change was not mfc'ed to 9.x, it isn't broken there.
progress information. The first is that fetch_read() (used in the HTTP
code but not the FTP code) can enter an infinite loop if it has previously
been interrupted by a signal. The second is that when it is interrupted,
fetch_read() will discard any data it may have read up to that point.
Luckily, both bugs are extremely timing-sensitive and therefore difficult
to trigger.
