Subject: [dpdk-stable] [PATCH v5 06/17] net/i40e/base: fix PF reset
Date: Fri,  8 Oct 2021 11:55:25 +0000	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

PF has to delete all the filters during reset.
If it is fully loaded with filters then it is possible that it will take
more than 200 ms to finish the reset resulting in timeout during pf_reset
and PF reset failed, -15 error indication.

Increasing the timeout value for PF reset from 200 to 1000 to give PF
more time to finish reset if it is loaded with filters.

Fixes: 1e32378f0774 ("i40e/base: increase PF reset max loop limit")
