Subject: [PATCH net-next 08/13] bnxt_en: Refactor bnxt_hwrm_set_coal()
Date: Fri, 27 Oct 2023 16:22:47 -0700 [thread overview]
Message-ID: <20231027232252.36111-9-michael.chan@broadcom.com> (raw)
In-Reply-To: <20231027232252.36111-1-michael.chan@broadcom.com>
[-- Attachment #1: Type: text/plain, Size: 2606 bytes --]
Add 2 helper functions to set coalescing for each RX and TX rings. This
will make it easier to expand the number of TX rings per MSIX in the
next patches.
