The code is not really tested yet due to lack of initiator support.

While this implementation is still not perfect, previous was just broken.

At this point we have nothing to report through that register.

Add support for PIO variants of READ/WRITE commands for AHCI disks.
AHCI API hides all PIO specifics, so this functionality is almost free.

Receive filter configuration is done in nge_rxfilter(). Remove
unnecessary filter configuration code in nge_init_locked().
While I'm here add a check for driver running state for multicast
filter handling. Also remove unnecessary assignment to error
variable since it is cleared in the function entry.

Fix a bug introdiced in r217548. According to NS DP83815 data
sheet, RX filter should be disabled before programming.
Previously it was clearing wrong bits so RX filter was not
disabled in RX filter configuration.

Enable receive filter in sis_rxfilter().
While I'm here add a check for driver running state for multicast
filter handling.

Allow the kern.osrelease and kern.osreldate sysctl values to be set in a
jail's creation parameters. This allows the kernel version to be reliably
spoofed within the jail whether examined directly with sysctl or
indirectly with the uname -r and -K options.
Export the new osreldate and osrelease jail parms in jail_get(2).
Fix line wrap.

sfxge: add barriers to BAR write macros
In theory the barriers are required to cope with write combining and
reordering. Two barriers are added (sometimes merged to one):
1. Before the first write to guarantee that previous writes to the region
have been done
2. Before the last write to guarantee that write to the last dword/qword is
done after previous writes
Barriers are inserted before in the assumption that it is better to
postpone barriers as much as it is possible (more chances that the
operation has already been already done and barrier does not stall CPU).
On x86 and amd64 bus space write barriers are just compiler memory barriers
which are definitely required.

sfxge: assert either kernel or internal copy of interface flags
ioctl to put interface down sets ifp->if_flags which holds the intended
administratively defined state and calls driver callback to apply it.
When everything is done, driver updates internal copy of
interface flags sc->if_flags which holds the operational state.
So, transmit from Rx path is possible when interface is intended to be
administratively down in accordance with ifp->if_flags, but not applied
yet and the operational state is up in accordance with sc->if_flags.

The synchronisation value returned by the so-called feedback endpoint
appears to be too inaccurate that it can be used to synchronize the
playback data stream. If there is a recording endpoint associated with
the playback endpoint, use that instead. That means if the isochronous
OUT endpoint is asynchronus the USB audio driver will automatically
start recording, if possible, to get exact information about the
needed sample rate adjustments. In no recording endpoint is present,
no rate adaption will be done.
While at it fix an issue where the hardware buffer pointers don't get
reset at the first device PCM trigger.
Make some variables 32-bit to avoid problems with multithreading.
Use the feedback value from the synchronization endpoint as fallback
when there is no recording channel.

sfxge: add common code support for changing TX queue pace
To delay packets from a particular TX queue by a particular time, write a value
into the TX Pace table s.t. pace time <= TX Pace Clock Period * (2 ^ pace value)
- the TX pace clock is 1/13 of the system clock, so its period should be 104 or
52 ns depending on whether turbo mode is active.
EFX_TX_PACE_CLOCK_BASE added by me.
