Subject: [dpdk-dev] [PATCH 1/3] net/txgbe: fix to get interrupt status
Date: Wed, 13 Oct 2021 10:45:19 +0800 [thread overview]
Message-ID: <20211013024521.20520-2-jiawenwu@trustnetic.com> (raw)
In-Reply-To: <20211013024521.20520-1-jiawenwu@trustnetic.com>
It's necessary to set 1 on TXGBE_PX_INTA register to get interrupts
normally, when legacy interrupt mode is used.
Fixes: 2fc745e6b606 ("net/txgbe: add interrupt operation")
Cc: stable@dpdk.org
