Subject: [next-queue v4 1/4] i40e: Store the irq number in i40e_q_vector
Date: Fri,  7 Oct 2022 14:38:40 -0700	[thread overview]
Message-ID: <1665178723-52902-2-git-send-email-jdamato@fastly.com> (raw)
In-Reply-To: <1665178723-52902-1-git-send-email-jdamato@fastly.com>

Make it easy to figure out the IRQ number for a particular i40e_q_vector by
storing the assigned IRQ in the structure itself.
