Subject: [PATCH 1/3] common/cnxk: optimize ethdev teardown time
Date: Tue, 5 Dec 2023 15:30:46 +0530 [thread overview]
Message-ID: <20231205100048.1387058-1-rkudurumalla@marvell.com> (raw)
API mbox_alloc_msg_npa_aq_enq() mbox is called if SQ needs
to be updated from mbox response else mbox call to kernel
is bypassed reducing the time taken to complete
roc_nix_tm_sq_aura_fc() function.This reduces ethdev
teardown time by 20%.
