The hardware rate limiting feature is enabled by the RATELIMIT kernel
option. Please refer to ifconfig(8) and the txrtlmt option and the
SO_MAX_PACING_RATE set socket option for more information. This
feature is compatible with hardware transmit send offload, TSO.
A set of sysctl(8) knobs under dev.mce.<N>.rate_limit are provided to
setup the ratelimit table and also to fine tune various rate limit
related parameters.

lists in the EFI memory map. As such we need to reduce the mappings to
restrict them to not be the full 1G block. For now reduce this to a 2M
block, however this may be further restricted to be 4k page aligned as
other SoCs may require.
This allows ThunderX2 to boot reliably to userspace without performing
any speculative memory accesses to invalid physical memory.
This is a recommit of r334035 now that we can access the EFI Runtime data
through the DMAP region.

If the check for a UFS partition at offset 0 on the disk fails, check
to see if there's a BSD disklabel at block 1 (standard) or at offset
512 (install images assume 512 sector size). If found, probe for UFS
on the 'a' partition.
This fixes UEFI booting images from a BSD labeled MBR slice when the
'a' partiton isn't at offset 0. This is a stop-gap fix since we plan
on removing boot1.efi in FreeBSD 12. We can't easily do that for 11.2,
however, hence the short MFC window.

The GMII control bit ETH_MAC_CR_GMII_EN_ is not documented in

by Microchip it is:
#define ETH_MAC_CR_GMII_EN (0x00080000UL ) // GMII/RGMII Selection
is that current one (mass storage device) doesn't work as it is - it
needs to be set to 0 after the LUN is configured, which is what the
cfumass rc script does. In other words: the current default does not
work, and to actually make it work it had to be set to -1 in
/boot/loader.conf.

Eliminate the same assertion, but spelled differently, at the end of
