When an mbuf allocation fails in the receive path, the mbuf containing the received packet is not sent to the host network stack and is reused again on the receive ring. Remaining received packets in the ring are not processed in that invocation of bxe_rxeof() and defered to the task thread
r275539:
cxgbe(4): Allow for different pad and pack boundaries for different
adapters. Set the pack boundary for T5 cards to be the same as the
PCIe max payload size. The chip likes it this way.
In this revision the driver allocate rx buffers that align on both
boundaries. This is not a strict requirement and a followup commit
will switch the driver to a more relaxed allocation strategy.
r275554:
cxgbe(4): allow the driver to use rx buffers that do not end on a pack
boundary.
Fix some bad interaction between cxgbe(4) and lacp lagg(4) that could
leave a port permanently disabled when a copper cable is unplugged and
then plugged right back in.
lacp_linkstate goes looking for the current ifmedia on a link state
change and it could get stale information from cxgbe(4) on a module
unplug followed by replug. The fix is to process module events before
link-state events within the driver, and to always rebuild the ifmedia
list on a module change event (instead of rebuilding it lazily).
Thanks to asomers@ for the problem report and detailed analysis to go
with it.
Fix thinko/copypaste error.
When checking the length of the mutual secret password the variable for
the secret password was used by mistake. This resulted in ctld never
warning about the length of the mutual secret being wrong even if it was.

Pull in r233552 from upstream libc++ trunk (by Eric Fiselier):
[libcxx] Fix PR22771 - Support access control SFINAE in the library
version of is_convertible.
Summary:
Currently the conversion check does not take place in a context where
access control SFINAE is applied. This patch changes the context of
the test expression so that SFINAE occurs if access control does not
permit the conversion.

Eliminate the gratuitous use of mmap(2) flags from the implementation

r280179:
Add LIB_CXX so that C++ libraries will use CXX to link.
This adds some extra dependencies directly to Makefile.inc1 as
atf is still a prebuild library in stable/10. If r273449 is MFCd

Document LIB and LIB_CXX.
When catopen(3) returns an error, it caches the result of that error from
r202992. The refcount on the cache entry is not initialized, so any attempt
to clean the cache will skip over this item since it likely has a >0 value.
This change is currently a NOP.

On some Intel CPUs with a P-state but not C-state invariant TSC the TSC
may also halt in C2 and not just C3 (it seems that in some cases the BIOS
advertises its C3 state as a C2 state in _CST). Just play it safe and
disable both C2 and C3 states if a user forces the use of the TSC as the
timecounter on such CPUs.

Add support for managing PCI bus numbers. As with BARs and PCI-PCI bridge
I/O windows, the default is to preserve the firmware-assigned resources.
PCI bus numbers are only managed if NEW_PCIB is enabled and the architecture
defines a PCI_RES_BUS resource type.
- Add a helper API to create top-level PCI bus resource managers for each
PCI domain/segment. Host-PCI bridge drivers use this API to allocate
bus numbers from their associated domain.
- Change the PCI bus and CardBus drivers to allocate a bus resource for
their bus number from the parent PCI bridge device.
- Change the PCI-PCI and PCI-CardBus bridge drivers to allocate the
full range of bus numbers from secbus to subbus from their parent bridge.
The drivers also always program their primary bus register. The bridge
drivers also support growing their bus range by extending the bus resource
and updating subbus to match the larger range.
- Add support for managing PCI bus resources to the Host-PCI bridge drivers
used for amd64 and i386 (acpi_pcib, mptable_pcib, legacy_pcib, and qpi_pcib).
- Define a PCI_RES_BUS resource type for amd64 and i386.
