From efbd16eadea870e01cf4518f425e3f7bdeb8a338 Mon Sep 17 00:00:00 2001 From: Ivan Malov Date: Mon, 28 Aug 2017 13:53:46 +0100 Subject: [PATCH] net/sfc: specify correct scale table size on Rx start efx_rx_scale_tbl_set() takes the number of entries in the scale table to be set, not the size of the table in bytes; currently this bug does not make any damage since the size argument is used to wrap the loop on the input table when filling in an MCDI request in case if the table size in the MCDI request is larger then one provided by the user, and MCDI scale table size is the same as the size of the table provided by the driver; this patch brings a fix for the bug Fixes: 4ec1fc3ba881 ("net/sfc: add basic stubs for RSS support on driver attach") Cc: stable@dpdk.org Signed-off-by: Ivan Malov Signed-off-by: Andrew Rybchenko --- drivers/net/sfc/sfc_rx.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/sfc/sfc_rx.c b/drivers/net/sfc/sfc_rx.c index 1bf86445b6..364f71816a 100644 --- a/drivers/net/sfc/sfc_rx.c +++ b/drivers/net/sfc/sfc_rx.c @@ -1068,7 +1068,7 @@ sfc_rx_rss_config(struct sfc_adapter *sa) goto finish; rc = efx_rx_scale_tbl_set(sa->nic, sa->rss_tbl, - sizeof(sa->rss_tbl)); + RTE_DIM(sa->rss_tbl)); } finish:
