Subject: [dpdk-dev] [PATCH v1 03/24] net/ena: add interrupt handler for admin queue
Date: Wed, 9 May 2018 14:45:47 +0200 [thread overview]
Message-ID: <20180509124552.22854-3-mk@semihalf.com> (raw)
In-Reply-To: <20180509124552.22854-1-mk@semihalf.com>
The ENA device is able to send MSI-X when it will complete an command
when polling mode is deactivated. Further, the same interrupt handler
will be used for the AENQ handling - services of the ENA device, that
allows to implement watchdog or lsc handler.
