CRITICAL FIX - with stats changes the older 82598 will panic
and trash the stack on driver load, FCOE registers ONLY exist
in 82599 and must not be read otherwise.
kern/153951 - to correct incorrect media type on adapters
with pluggable modules I have eliminated the old static
table in favor of a new dynamic shared code routine. This
also has the benefit of detecting changes when a different
module is inserted.
Performance/enhancement to the Flow Director code from my
linux coworker (the developer of the code).
Fixes from Michael Tuexen - a data corruption problem on the
82599 (CRITICAL), fix so the buf size correctly adjusts as
the cluster changes, and max descriptors are set properly.
Also added 16K clusters for those REALLY big jumbos :)
In the RX path, the RX LOCK was not being released, and this
causes LOR problems. Add the code that igb already has.
Sync with in house shared code, this was necessary for the
Flow Director fix.

requires all SYSCTL setups to specify a type. Most of them are now
checked at compile-time.
Remove SYSCTL_*X* sysctl additions as the print being in hex should be
controlled by the -x flag to sysctl(8).

DP8381[56] and SiS 900/7016 controllers. After r212119, sis(4) no
longer reinitializes controller if ALLMULTI/PROMISC was changed.
However, RX filter handling code assumed some bits of the RX filter
is programmed by driver initialization. This caused ALLMULTI/PROMISC
configuration is ignored under certain conditions.
Fix that issue by reprogramming all bits of RX filter register.
While I'm here follow recommended RX filter programming steps
recommended by National DP8381[56] data sheet(RX filter should be
is disabled before programming).

can just assume it implements pcib IVARs, and all pcib devices have a

GbE controllers. It seems these controllers no longer support
multi-fragmented RX buffers such that driver have to allocate
physically contiguous buffers.
o Retire RL_FLAG_NOJUMBO flag and introduce RL_FLAG_JUMBOV2 to
mark controllers that use new jumbo frame scheme.
o Configure PCIe max read request size to 4096 for standard frames
and reduce it to 512 for jumbo frames.
o TSO/checksum offloading is not supported for jumbo frames on
these controllers. Reflect it to ioctl handler and driver
initialization.
o Remove unused rl_stats_no_timeout in softc.
o Embed a pointer to structure rl_hwrev into softc to keep track
of controller MTU limitation and remove rl_hwrev in softc since
that information is available through a pointer to structure
rl_hwrev.

limit maximum RX buffer size to RE_RX_DESC_BUFLEN instead of
blindly configuring it to 16KB. Due to lack of documentation, re(4)
didn't allow jumbo frame on these controllers. However it seems
controller is confused with jumbo frame such that it can DMA the
received frame to wrong address instead of splitting it into
multiple RX buffers. Of course, this caused panic.
Since re(4) does not support jumbo frames on these controllers,
make controller drop frame that is longer than RE_RX_DESC_BUFLEN
sized frame. Fortunately RTL810x controllers, which do not support
jumbo frame, have no such issues but this change also limited
maximum RX buffer size allowed to RTL810x controllers. Allowing
16KB RX buffer for controllers that have no such capability is
meaningless.

the command unless MAC is enabled so DUMP request for down
interface caused request timeout.
RealTek changed TX descriptor format for later controllers so these
controllers require MSS configuration in different location of TX
descriptor. TSO is enabled by default for controllers that use new
descriptor format.
For old controllers, TSO is still disabled by default due to broken
frames under certain conditions but users can enable it.

These controllers consist of two Marvell 88SE9128 6Gbps SATA chips and
PLX PCIe bridge. As result, they seem to be agree to work with ahci(4)
as usual HBAs. The only noticed issue is that RAID BIOS disables all
drive caches during boot, though `camcontrol cmd ...` is able to fix that.
Those who wants RAID functionality can still use closed proprietary driver
