The size limits came from a flawed understanding of dump records.
The real issue was that dump was bogusly interpreting c_count
sometimes. r334978 fixes that.
We shouldn't count the bytes set in c_addr for TS_CLRI and TS_BITS
nodes. Those block overload c_count to communicate how many blocks
follow, not now many c_addr spaces are used. Dump would dump core
(now) because memory layout moved around and we'd access elements past
the end to make a count.

lan78xx_eeprom_read just checked for EEPROM presence then called
lan78xx_eeprom_read_raw if present, and had only one caller. Introduce
lan78xx_eeprom_present to check for EEPROM presence, and use it in the
one place it is needed.
This is used by r334964, which was accidentally committed out-of-order
from my work tree.

Add some asserts that prevents the overflows of c_addr. This can't
happen, absent bugs. However, certain large filesystems can cause
problems. These have been prevented by r334968, but a solution
is needed. These asserts will help assure that solution is correct.

There were a couple of cases in newnfs_request() that it assumed that it
was an NFSv4.1 mount with a session. This should always be the case when
a Sequence operation is in the reply or the server replies NFSERR_BADSESSION.
However, if a server was broken and sent an erroneous reply, these safety
belt checks should avoid trouble.
The one check required a small tweak to nfsmnt_mdssession() so that it
returns NULL when there is no session instead of the offset of the field
in the structure (0x8 for i386).
This patch should have no effect on normal operation of the client.
Found by inspection during pNFS server development.

Differences between LAN7800 and LAN7850 from the driver's perspective:
* The LAN7800 muxes EEPROM signals with LEDs, so LED mode needs to be
disabled when reading/writing EEPROM. The EEPROM is not muxed on the
LAN7850.
* The Linux driver enables automatic duplex and speed detection when
there is no EEPROM, for the LAN7800 only. With this FreeBSD driver
LAN7850-based adapters without a configuration EEPROM fail to link
(with or without the automatic duplex and speed detection code), so
I have just followed the example of the Linux driver for now.

At present, RACK requires the TCPHPTS option to run. However, because
modules can be moved from machine to machine, this dependency is really
best assessed at load time rather than at build time.

Casting from rman_res_t to a pointer results in "cast to pointer from
integer of different size" warnings with base gcc on i386, so print
these without casting. The kva field of struct bxe_bar is of type
vm_offset_t, which can be 32 or 64 bit, so cast it to uintmax_t before
printing.

Base gcc fails to compile sys/dev/drm2/i915/intel_display.c for i386,
with the following -Werror warnings:
cc1: warnings being treated as errors
/usr/src/sys/dev/drm2/i915/intel_display.c:8884: warning:
initialization from incompatible pointer type
This is due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36432, which
incorrectly interprets the [] as a flexible array member.
Because base gcc does not have a -W flag to suppress this particular
warning, it requires a rather ugly cast. To not influence any other
compiler, put it in a #if/#endif block.

dteske@, I believe, had originally pointed out that lualoader failed to
allow logo-*.lua for new logos to be added. When correcting this mistake, I
failed to do the same for brands.
Correct the sub-mistake: creating new brands is almost identical to creating
new logos, except one must use `drawer.addBrand` and 'graphic' is the only
valid key for a branddef at the moment.
While here, I've added `drawer.default_brand` to be set to name of brand to
be used (e.g. 'fbsd', project default).
Eventually this whole goolash will be documented.

This is all that is left from an attempt to build a (sub-)minimal kernel
