There is no strong need for pulling in linux/if_ether.h here since all
that is needed if ETH_P_IP and we already cover multiple other ETH_P_*
values in utils/common.h.

The addition operator is of higher precedence than the ternary
conditional and the construction here needs to use parentheses to
calculate the buffer length properly when generating test frames with
BIP protection.

This makes it easier to do live parsing of captured pcap files from
wlantest without having to rename and restart the capture file. Packet
writes are flushed to disk after each packet if -N is included in the
command line.

tdls_verify_mic() and tdls_verify_mic_teardown() could have tried to
read the 16-octet FTIE MIC when processing a TDLS frame even if the
received FTIE is truncated. At least in theory, this could result in
reading couple of octets beyond the frame buffer.

These functions did not verify that the received frame is long enough to
contain the beginning of the variable length IE area. A truncated frame
could have caused a segmentation fault due to reading beyond the buffer.

These were somewhat more hidden to avoid direct use, but there are now

Relative time shouldn't be calculated based on gettimeofday
because that clock can jump (e.g., when the time is adjusted
by the system administrator.)
On systems where that is available, use CLOCK_BOOTTIME (on
fairly recent Linux systems, this clock takes into account
the time spend suspended) or CLOCK_MONOTONIC (on Linux and
some POSIX systems, this clock is just freely running with
no adjustments.)

A text file with a hexdump of PTK (KCK|KEK=TK with 48 octets for CCMP or
64 octets for TKIP or alternative 16 or 32 octet TK for CCMP/TKIP) can

the current known PTK fails to decrypt a frame (or if no current PTK is
known) all listed PTKs are iterated to see if any of them matches.

Some corner cases may result in both directions of TDLS tracking context
existing. If that is the case, the incorrect one may end up getting
picked when figuring out which TK to use for decryption or fix

The new -n<file> command line argument can be used to request wlantest
