From 5656ac5542df5842d9e581546aab19cd83222b32 Mon Sep 17 00:00:00 2001 From: Jose Abreu Date: Wed, 7 Aug 2019 10:03:10 +0200 Subject: [PATCH] net: stmmac: xgmac: Implement set_mtl_tx_queue_weight() Implement the TX Queue Weight callback. In order for this to be active we also need to set ETS algorithm when configuring Queue. Signed-off-by: Jose Abreu Signed-off-by: David S.
