When taking events from a port, we checked the history list to check if the
event needed to be put back in order i.e. originally came from a reordered
queue type. The check for reordering involved checking if the reorder
buffer entry pointer was null. However, after that pointer was used it was
never cleared to null again.
This caused problems when we had mixed reordered and atomic or parallel
events, as the events from the latter two queue types were misidentified as
needing reordering. This let in some cases to crashes, but mostly led to
dropping events, and then application lock-up.

The link status is queried by link_update callback when LSC is disabled.

Instead of doing (the heavy) reset at stop, this patch introduced a flag,

rte_eth_dev_configure: ethdev port_id=4 \
max_rx_pkt_len 9018 > max valid value 2048
It's expected that slaves will be added to bonded device inside
'rte_eth_dev_configure' and proper 'max_rx_pktlen' configured
for all of them.
Failure happens because of hardcoded low value of 'max_rx_pktlen'.
Increasing of this value to ETHER_MAX_JUMBO_FRAME_LEN will allow
above scenario (attach + configure).
It is important because it is the way OVS wants to work with

On RX path, after receiving bunch of packets, variable tracking
available descriptors in HW queue was not updated.
To fix this issue, variable tracking used descriptors must be updated
after receiving packets - it must be reduced by the amount of received
descriptors in current batch.
Additionally, variable next_to_clean in rx_ring must be updated before
entering ena_populate_rx_queue() to keep it up to date with the current
ring state.
