While I'm here do not set RX checksum bits in RX descriptor
initialization. It is controller's job to set these bits.

The existing code only checked the alignment of the first mbuf and
didn't enforce the size constraints.
This commit introduces a simple function to check the alignment and
size of all mbufs in the list. This fixes the initial issue in the
PR.

do on i386. The consequences of not doing so on amd64 became apparent
with the introduction of the COUNT_IPIS and COUNT_XINVLTLB_HITS
options. Specifically, single-threaded applications were generating
unnecessary IPIs to shoot-down the TLB on other processors. However,
this is clearly nonsensical because a single-threaded application is
only running on the current processor. The reason that this happens
is that pmap_activate() is unable to properly update the old pmap's
field "pm_active" without the correct "curpmap". So, in effect, stale
bits in "pm_active" were leading pmap_protect(), pmap_remove(),
pmap_remove_pages(), etc. to flush the TLB contents on some arbitrary
processor that wasn't even running the same application.

the same fix present in NetBSD.
Note: the getopt man page contains more antique information like this.
An overhaul of the man page and/or sync with NetBSD would be the right
thing to do. But since this is out of the scope of the PR, I'll leave
it as it is for now.

Bump / to 1GB, /var to 4GB and /tmp to 1GB.
A 512MB root partition is now too small to hold two kernels, so to
prevent installkernel failing 1GB is a better default. Likewise,
applications are storing more data in /var so 4GB is more reasonable
on a modern machine.
The previous minimum partition sizes were too small to hold a minimal
installation, and have been adjusted accordingly.

it to configure the interface. When the script is complete, dhclient
monitors the routing socket and will terminate if its address is
deleted or if its interface is removed or brought down.
Because the routing socket is already open when dhclient-script is
run, dhclient ignores address deletions for 10 seconds after the
script was run.
If the address that will be obtained is already configured on the
interface before dhclient starts, and if dhclient-script takes more
than 10 seconds (perhaps due to dhclient-*-hooks latencies), on script
completion, dhclient will immediately and silently exit when it sees
the RTM_DELADDR routing message resulting from the script reassigning
the address to the interface.
This change logs dhclient's reason for exiting and also changes the
10 second timeout to be effective from completion of dhclient-script
rather than from when it was started.
We now ignore RTM_DELADDR and RTM_NEWADDR messages when the message
contains no interface address (which should not happen) rather than
exiting.
