Subject: [dpdk-stable] [PATCH] net/i40e: fix vf resource leakage problem
Date: Sat, 21 Aug 2021 16:14:26 +0800	[thread overview]
Message-ID: <> (raw)

From: Qiming Chen <>

In the i40evf_dev_init function, when the MAC memory alloc fails, the
previously initialized vf resource is not released, resulting in leakage.
The patch calls the i40evf_uninit_vf function in the abnormal branch to
release resources.

Fixes: 5c9222058df7 ("i40e: move to drivers/net/")
