From ee3e875f10fca68fb7478c23c75b553e56da319c Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sat, 17 Apr 2021 00:22:21 +0300 Subject: [PATCH] net: enetc: increase TX ring size Now that commit d6a2829e82cf ("net: enetc: increase RX ring default size") has increased the RX ring size, it is quite easy to congest the TX rings when the traffic is predominantly XDP_TX, as the RX ring is quite a bit larger than the TX one. Since we bit the bullet and did the expensive thing already (larger RX rings consume more memory pages), it seems quite foolish to keep the TX rings small. So make them equally sized with TX.
