Users can create the desired number of RxQ and TxQ in DPDK. For
example, if the number of RxQ = 2 and the number of TxQ = 5,
a total of 8 file descriptors will be created for a tap device,
including RxQ, TxQ, and one for keepalive. The RxQ and TxQ
with the same ID are paired by dup(2).
In this scenario, Kernel will have 3 RxQ where packets are
incoming but not read. The reason for this is that there are only
2 RxQ that are polled by DPDK, while there are 5 queues in Kernel.
This patch add a checking if DPDK has appropriate numbers of
queues to avoid unexpected packet drop.

If hardware supports IEEE 1588 PTP, PTP capability will be set.
Currently, vec and sve burst is unsupported when PTP capability is set.
For sake of Rx/Tx performance, IEEE 1588 PTP is not supported in sve or
vec burst mode. When enabling IEEE 1588 PTP, Rx/Tx burst mode should be
simple or common. Rx/Tx burst mode could be set like this, for example:
-a 0000:35:00.0,rx_func_hint=common,tx_func_hint=common
This patch supports vec and sve burst when PTP is disabled. And only
support simple or common burst When PTP is enabled.

Add external clock support for cnxk timer adapter.
External clock mapping is as follows:
RTE_EVENT_TIMER_ADAPTER_EXT_CLK0 = TIM_CLK_SRC_10NS,
RTE_EVENT_TIMER_ADAPTER_EXT_CLK1 = TIM_CLK_SRC_GPIO,
RTE_EVENT_TIMER_ADAPTER_EXT_CLK2 = TIM_CLK_SRC_PTP,
RTE_EVENT_TIMER_ADAPTER_EXT_CLK3 = TIM_CLK_SRC_SYNCE,
TIM supports clock input from external GPIO, PTP, SYNCE clocks.
Input resolution is adjusted based on CNTVCT frequency for better
estimation.
Since TIM is unaware of input clock frequency, application is
expected to pass the frequency.
Example:
-a 0002:0e:00.0,tim_eclk_freq=122880000-0-0
The order of frequencies above is GPIO-PTP-SYNCE.

Since we allow line lengths of up to 100, and the CI checkpatches job
only check for that amount, the rest of our tooling and docs should
reflect this reality. Therefore we can:
* adjust the editorconfig to use that value, to save editors (e.g. vim)
from automatically wrapping lines at 80 characters when typing.
[Since python checkers all seem to expect 79 character lines max, add
for python only a 79-char max line length.]
* change the default line length setting in checkpatches script to 100
so as it matches CI and pre-merge checks.
* update the docs to clarify that while 80 chars is recommended, up to
100 characters is acceptable.
