People tweaking the build system or compilers tend to look into

in the Makefile and some in the source code is surprising.
Pragmas have the advantage that they leave the warnings enabled

1. Edit /etc/ncd.conf to adjust the cache timeouts as follows:
positive-time-to-live hosts 30
negative-time-to-live hosts 1
2. Ensure that nsswitch.conf hosts line contains something like:
hosts: files cache dns
Note that cache must be specified before dns.
3. Start nscd.
4. Run the following command:

5. While running the command, remove or comment out all nameserver

Metadata printing with -b, -H, or -n flags suffered from a few flaws:
1) -b/offset printing was broken when used in conjunction with -o
2) With -o, bsdgrep did not print metadata for every match/line, just
the first match of a line
3) There were no tests for this
Address these issues by outputting this data per-match if the -o flag is
specified, and prior to outputting any matches if -o but not --color,
since --color alone will not generate a new line of output for every
iteration over the matches.
To correct -b output, fudge the line offset as we're printing matches.
While here, make sure we're using grep_printline in -A context. Context
printing should *never* look at the parsing context, just the line.
The tests included do not pass with gnugrep in base due to it exhibiting
similar quirky behavior that bsdgrep previously exhibited.

We should not set an arbitrary cap on the number of matches on a line,
and in any case MAX_LINE_MATCHES of 32 is much too low. Instead, if we
match more than MAX_LINE_MATCHES, keep processing and matching from the
last match until all are found.
For the regression test, we produce 4096 matches (larger than we expect
we'll ever set MAX_LINE_MATCHES) and make sure we actually get 4096
lines of output with the -o flag.
We'll also make sure that every distinct line is getting its own line
number to detect line metadata not being printed as appropriate along
the way.

When doing AMSDU offload, the driver (for now!) presents 802.11 frames with
the same sequence number and crypto sequence number / IV values up to the stack.
But, this will trip afoul over the sequence number detection.
So drivers now have a way to signify that a frame is part of an offloaded
AMSDU group, so we can just ensure that we pass those frames up to the
stack.
The logic will be a bit messy - the TL;DR will be that if it's part of
the previously seen sequence number then it belongs in the same burst.
But if we get a repeat of the same sequence number (eg we sent an ACK
but the receiver didn't hear it) then we shouldn't be passing those frames
up. So, we can't just say "all subframes go up", we need to track
whether we've seen the end of a burst of frames for the given sequence
number or not, so we know whether to actually pass them up or not.
The first part of doing all of this is to ensure the ieee80211_rx_stats
struct is available in the RX sequence number check path and the
RX ampdu reorder path. So, start by passing the pointer into these
functions to avoid doing another lookup.
The actual support will come in a subsequent commit once I know the
functionality actually works!
r313948 partially fixed --mmap behavior but was incomplete. This commit
generally reverts it and does it the more correct way- by just consuming

When creating EQs to handle CQ completion events for the PF or for
VFs, we create enough EQE entries to handle completions for the max
number of CQs that can use that EQ.
When SRIOV is activated, the max number of CQs a VF (or the PF) can
obtain is its CQ quota (determined by the Hypervisor resource
tracker). Therefore, when creating an EQ, the number of EQE entries
that the VF should request for that EQ is the CQ quota value (and not
the total number of CQs available in the firmware).
Under SRIOV, the PF, also must use its CQ quota, because the resource
tracker also controls how many CQs the PF can obtain.
Using the firmware total CQs instead of the CQ quota when creating EQs
resulted wasting MTT entries, due to allocating more EQEs than were
needed.

(TS) method is used. When packet timestamp is used, the "current_qdelay"
keeps storing the last queue delay value calculated in the dequeue
function. Therefore, when a burst of packets arrives followed by
a pause, the "current_qdelay" will store a high value caused by the
burst and stick to that value during the pause because the queue
delay measurement is done inside the dequeue function. This causes
the drop probability calculation function to calculate high drop
probability value instead of zero and prevents the burst allowance
mechanism from working properly. Fix this problem by resetting
"current_qdelay" inside the drop probability calculation function
when the queue length is zero and TS option is used.

Care must be taken that the resulting ifmedia_active is identical to
what the PHY will compute, or gratuitous link status changes will
occur whenever the PHYs update function is called.
This patch implements above improvement. On the occasion set a pointer to
