With autodetection turned on, hitting the filesystem everytime we need to
calculate choices for the kernel carousel is kind of slow. Cache once on the
first listing and reload it anytime the config is reloaded in case any of
the loader.conf(5) changes that affect this (kernel, kernels,
kernels_autodetect) have changed. This also picks up the case where we've
changed currdev and the autodetected kernels could change.
Usually this is just ignored:

/usr/bin/ld: skipping incompatible /scratch/obj/root/git/freebsd/amd64.amd64/obj-lib32/lib/libz/libz.a when searching for -lz
However some combination of newer toolchains simply fail here instead:
/usr/bin/ld: error: /home/dstolfa/obj/home/dstolfa/cadets/amd64.amd64/obj-lib32/lib/libz/libz.so is incompatible with /usr/lib/crt1.o
Libz is not needed for mkmagic so just exclude it.

These test cases cover all of the basic TFTP protocol, but not the optional
parts.

jeggleston - LRO eating window updates
Based on all of the above I think we are RFC compliant doing it this way:
https://tools.ietf.org/html/rfc1122
section 4.2.2.16
"Note that TCP has a heuristic to select the latest window update despite
possible datagram reordering; as a result, it may ignore a window update with
a smaller window than previously offered if neither the sequence number nor the
acknowledgment number is increased."

The lookup_host() helper subroutine emits a struct in_addr value in network
byte order via caller passed pointer. However, the table value is expected
to be stored in host byte order. On little-endian machines, this produced a
reversed endian table value for Legacy or IPv4 table types when the value
was a hostname (instead of a plain IP address).
Fix by using ntohl() on the output 32-bit address.
While here, avoid some aliasing violations by storing the lookup_host()
output in an intermediate object of the correct type.

There is a difference when parsing a completion entry between Ethernet
and IB ports. When link layer is Ethernet the bits describe the type of
L3 header in the packet. In the case when link layer is Ethernet and VLAN
header is present the value of SL is equal to the 3 UP bits in the VLAN
header. If VLAN header is not present then the SL is undefined and consumer
of the completion should check if IB_WC_WITH_VLAN is set.
While that, this patch also fills the vlan_id field in the completion if
present.

Do not consider the inability to create a firmware dump fatal, but
inform about the situation and allow the driver to attach. The device
might not implement the needed VSC, or we might not know the layout of
the registers map. In either case, only firmware dump functionality is
limited, the network operations should be fine.

When the mlx5en(4) driver was converted to using BUSDMA(9) the call to
m_defrag() was moved after the part of the TX routine that strips the
header from the mbuf chain. Before it called m_defrag it first trimmed
off the now-empty mbufs from the start of the chain. This has the side
effect of also removing the head of the chain that has M_PKTHDR set.
m_defrag() will not defrag a chain that does not have M_PKTHDR set,
thus it was effectively never defragging the mbuf chains.
As it turns out, trimming the mbufs in this fashion is unnecessary since
the call to bus_dmamap_load_mbuf_sg doesn't map empty mbufs anyway, so
remove it.

Set and report vport MTU rather than physical MTU,
The driver will set both vport and physical port mtu
and will rely on the query of vport mtu.
SRIOV VFs have to report their MTU to their vport manager (PF),
and this will allow them to work with any MTU they need
without failing the request.
Also for some cases where the PF is not a port owner, PF can
work with MTU less than the physical port mtu if set physical
port mtu didn't take effect.

ConnectX-4/5 devices in mlx5core.
The dump is obtained by reading a predefined register map from the
non-destructive crspace, accessible by the vendor-specific PCIe
capability (VSC). The dump is stored in preallocated kernel memory and
managed by the mlx5tool(8), which communicates with the driver using a
character device node.
The utility allows to store the dump in format
<address> <value>
into a file, to reset the dump content, and to manually initiate the
dump.
A call to mlx5_fwdump() should be added at the places where a dump
must be fetched automatically. The most likely place is right before a
firmware reset request.
