[PATCH 1/8] net/qede: fix to disable per-VF Tx switching feature

[Rasesh Mody]

From: Harish Patil <harish.patil@cavium.com>

Provide a knob to control per-VF Tx switching feature by adding a config
option, CONFIG_RTE_LIBRTE_QEDE_VF_TX_SWITCH. By default, it will be kept
in disabled state for better performance with small sized frames.

[PATCH 3/8] net/qede: fix to update device link structure

[Rasesh Mody]

8ea656f8c app/testpmd: request link status interrupt
requires QEDE PMD to populate the device link structure without
having to query the driver for link status change event.
This patch updates the device link structure when link status event is
received.
Remove unused param from qed_link_update()

We should remove all compile-time options because they cannot be used
when DPDK is pre-packaged.
That's why the rule is "NO NEW COMPILE TIME OPTION".

After discussion with Ferruh, this patch is accepted as a hotfix.
But this option is expected to be removed quickly.
I've sent a patch to remove this option in 18.02:
	http://dpdk.org/ml/archives/dev/2017-November/081488.html
It gives you some time to supersede my patch by introducing a
run-time driver option.

Thanks

Hi Thomas,
Sure, thanks, we will address before 18.02-rc1.
Do you have any example on how to add a run-time driver option?
Does it mean to introduce some change in ethdev?
Thanks.

It is done by parsing devargs with rte_kvargs.
Examples:
	http://dpdk.org/commit/447e0d379
	http://dpdk.org/commit/001a520e4
