Currently when we enable/disable all Rx queues we do the following sequence for each Rx queue and then move to the next queue. 1. Enable/Disable the Rx queue via register write. 2. Read the configuration register to determine if the Rx queue was enabled/disabled successfully. In some cases enabling/disabling queue 0 fails because of step 2 above. Fix this by doing step 1 for all of the Rx queues and then step 2 for all of the Rx queues. Also, there are cases where we enable/disable a single queue (i.e. SR-IOV and XDP) so add a new function that does step 1 and 2 above with a read flush in between. This change also required a single Rx queue to be enabled/disabled with and without waiting for the change to propagate through hardware. Fix this by adding a boolean wait flag to the necessary functions. Also, add the keywords "one" and "all" to distinguish between enabling/disabling a single Rx queue and all Rx queues respectively.
