doc: fix grammar

Browse Source 
This patch corrects a grammatical error by changing 'an DPDK' to 'a DPDK',
so that the sentences can become grammatically accurate.

Fixes: 2e486e2632 ("doc: remove Intel references from linux guide")
Fixes: 48624fd96e ("doc: remove Intel references from prog guide")
Fixes: e0c7c47319 ("doc: remove Intel references from sample apps guide")

Since these logical core numbers, and their mapping to specific cores on specific NUMA sockets, can vary from platform to platform,
it is recommended that the core layout for each platform be considered when choosing the coremask/corelist to use in each case.
On initialization of the EAL layer by an DPDK application, the logical cores to be used and their socket location are displayed.
On initialization of the EAL layer by a DPDK application, the logical cores to be used and their socket location are displayed.
This information can also be determined for all cores on the system by examining the ``/proc/cpuinfo`` file, for example, by running cat ``/proc/cpuinfo``.
The physical id attribute listed for each processor indicates the CPU socket to which it belongs.
This can be useful when using other processors to understand the mapping of the logical cores to the sockets.

While the threads used by an DPDK application are pinned to logical cores on the system,
While the threads used by a DPDK application are pinned to logical cores on the system,
it is possible for the Linux scheduler to run other tasks on those cores also.
To help prevent additional workloads from running on those cores,
it is possible to use the ``isolcpus`` Linux kernel parameter to isolate them from the general Linux scheduler.

For such PMDs, any network ports under Linux* control will be ignored and cannot be used by the application.

This application includes a P-state power management algorithm to generate a frequency hint to be sent to CPUFreq.
The algorithm uses the number of received and available Rx packets on recent polls to make a heuristic decision to scale frequency up/down.
Specifically, some thresholds are checked to see whether a specific core running an DPDK polling thread needs to increase frequency
Specifically, some thresholds are checked to see whether a specific core running a DPDK polling thread needs to increase frequency
a step up based on the near to full trend of polled Rx queues.
Also, it decreases frequency a step if packet processed per loop is far less than the expected threshold
or the thread's sleeping time exceeds a threshold.
