0b4aefec80 add a warning in checksum offload that hardware TCP segmentation might be 
slow

on I219 I observe about 35% transmit performance drop when tso4 enabled

a1d10a8d03 actually writing always the checksum offload context descriptor 
makes the hw do extra processing, avoid doing that if possible -
on my computer with I219 this results in about 2% speedup in Tx performance

change adoped from FreeBSD

XXX should be also done for multiqueue case, but I don't have hw to test it

1352bf2652 Revert previous change to use SYSCTL_SETUP since it breaks on macppc. 
For some reason, the crypto module fails to link, and this results in
opencrypto sysctl failures.

Should resolve PR kern/55154

middle-end/94479 - fix gimplification of address

    When gimplifying an address operand we may expose an indirect
    ref via DECL_VALUE_EXPR for example.  This is dealt with in the
    code already but it fails to consider that INDIRECT_REFs get
    gimplified to MEM_REFs.

    Fixed which makes the ICE observed on x86_64-netbsd go away.

            * gimplify.c (gimplify_addr_expr): Also consider generated
            MEM_REFs.

            * gcc.dg/torture/pr94479.c: New testcase.

Fixes -fstack-check ICE when building devel/git-base.

ebe3e284a8 use PMAP_PAGE_INIT() to initialize mutex in pmap_page. 
VM_MDPAGE_INIT() in pmap_free_pdp() had initialized pp_flags,
so it unintentionally cleared PMAP_PAGE_FLAGS_PV_TRACKED.
use PMAP_PAGE_INIT to avoid using PMAP_PAGE_FLAGS_PV_TRACKED.

b0f199cb12 Exit successfully after printing the search path, stop further processing. 
Continuing to process had the unintended effect that `man` failed to find
a matching manual page for {EMPTY LIST OF REQUESTED MANUAL PAGES}, and
exited with 1.

Prompted by a fish shell snippet that tried and failed to distinguish between
FreeBSD man (-p takes argument) and NetBSD man (-p no argument) by comparing
`man -p` exit code.

ok riastradh, logix (which also pointed out the manual page SYNOPSIS is
saying man -p should be used this way).
