From b58398d9f85bb959fb7f1ec208a637ff4827cbab Mon Sep 17 00:00:00 2001 From: Shahaji Bhosle Date: Sat, 25 Apr 2020 09:17:25 +0530 Subject: [PATCH] net/bnxt: add Truflow flush-timer to alloc table scope Updated the params list to include flush timer, this will allow users to set the HW flush timer value in 10th of second. Setting 0 will disable the pending cache flush feature.
