hopefully a 2021c release reflecting it, only merge the DST changes for
Jordan and Samoa. This corrects present and future timestamps in those

ipmi(4): Limit maximum watchdog pre-timeout interval.
Previous code by default setting pre-timeout interval to 120 seconds
made impossible to set timeout interval below that, resulting in error
0xcc (Invalid data field in Request) at least on Supermicro boards.
To fix that limit maximum pre-timeout interval to ~1/4 of the timeout
interval, that sounds like a reasonable default: not too short to fire
too late, but also not too long to give many false reports.

e1000: Fix up HW vlan ops
2796f7ca:
* Don't reset the entire adapter for vlan changes, fix up the problems
* Add some functions for vlan filter (vfta) manipulation
* Don't muck with the vfta if we aren't doing HW vlan filtering
* Disable interrupts when manipulating vfta on lem(4)-class NICs
* On the I350 there is a specification update (2.4.20) in which the
suggested workaround is to write to the vfta 10 times (if at first you
don't succeed, try, try again). Our shared code has the goods, use it
* Increase a VF's frame receive size in the case of vlans
From the referenced PR, this reduced vlan configuration from minutes
to seconds with hundreds or thousands of vlans and prevents wedging the
adapter with needless adapter reinitialization for each vlan ID.
When handling a data irq, the sdhci driver calls the
sdhci_platform_will_handle() method, to determine if it should allow the
platform driver to handle the transfer or fall back to programmed I/O.
While dumping, the data irq path may be invoked directly (not from an
interrupt context), which the bcm2835_sdhci DMA code is not prepared to
handle. Return early in this case, to force the fallback to PIO.
Otherwise, the KASSERT that follows will be triggered, and the dump will
fail. On non-INVARIANTS kernels, the system will hang, waiting for a DMA
interrupt that will never arrive.
