The ENA driver was updated with the new features and few fixes and minor
changes are introduced.
First of all, the communication layer which is delivered by vendor was
updated - the version in the HEAD is a bit outdated now. ENA is able to
communicate with the driver through Admin queue by using admin interrupts
instead of polling.
Admin interrupts are also used for handling AENQ events, which are used for
the following new features:
- LSC handlers
- watchdog and device rest
- monitoring the admin queue
- handling ENA notifications (getting hints from device)
For the watchdog and admin queue monitoring, the timers had to be used, so
the makefile was modified to do not cut out the librte_timer.
>From other fixes and changes:
- legacy LLQ was removed which is now deprecated API
- Rx out of order completion was added to enable cleaning up packets out
of order
- Tx mbufs are now linearized if they exceed supported number of segments
- pass information about maximum number of Tx and Rx descriptors
- the IO queue number is now taking into consideration maximum number of
sq and cq
- Tx id requested for sending is now being validated and the reset is
being triggered if it is invalid
- branch predictioning was added for better performance
- error checking and returned values were fixed
- macros for allocating memory in communication layer were fixed
- information about numa mode is now being passed to the NIC

Hi Michał,
This arrived too late for this release cycle, let us close this release first
and consider set for next release.
Thanks,
ferruh
