This patch resolves an issue where the logic used to detect changes in rx-usecs
was incorrect and was masked by the call to ixgbe_update_rsc().
Setting rx-usecs between 0,2-9 and 1,10 and up requires a reset to allow

commit fa44f2f185 broke reloading of igb, when

resulting in a null pointer exception when accessing adapter->vf_data in
igb_reset() on module reload.

2. A follow up issue, pci_enable_sriov() should only be called if no VFs were
still allocated on module unload. Otherwise pci_enable_sriov() gets called
multiple times in a row rendering the NIC unusable until reset.
3. simply calling igb_enable_sriov() in igb_probe_vfs() is not enough as the
interrupts need to be re-setup. Switching that to igb_pci_enable_sriov().

Allocate the queue pairs individually instead of as a group. This
allows for much easier queue management as it is possible to dynamically
resize the queues without having to free and allocate the entire block.
Ease statistic collection by treating Tx/Rx queue pairs as a single
unit. Each pair is allocated together and starts with a Tx queue and
ends with an Rx queue. By ordering them this way it is possible to know
the Rx offset based on a pointer to the Tx queue.

This makes it so that the Tx and Rx byte and packet counts are
separated from the rest of the statistics. This allows for better
isolation of these stats when we move them into the 64 bit statistics.
Simplify things by re-ordering how the stats display in ethtool.
Instead of displaying all of the Tx queues as a block, followed by all
the Rx queues, the new order is Tx[0], Rx[0], Tx[1], Rx[1], ..., Tx[n],
Rx[n]. This reduces the loops and cleans up the display for testing
purposes since it is very easy to verify if flow director is doing the
right thing as the Tx and Rx queue pair are shown in pairs.

Avoid directly incrementing next_to_use for multiple reasons. The main
reason being that if we directly increment it then it can attain a state
where it is equal to the ring count. Technically this is a state it
should not be able to reach but the way this is written it now can.
This patch pulls the value off into a register and then increments it
and writes back either the value or 0 depending on if the value is equal
to the ring count.

But eee_set_cur also calls eee_get_cur and it did not zero the input
