From 3132d2827d92c2ee47fdf4dbec75bba0a2f291cb Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Sat, 5 May 2012 02:31:23 +0100 Subject: [PATCH] sfc: Fix division by zero when using one RX channel and no SR-IOV If RSS is disabled on the PF (efx->n_rx_channels == 1) we try to set up the indirection table so that VFs can use it, setting efx->rss_spread = efx_vf_size(efx). But if SR-IOV was disabled at compile time, this evaluates to 0 and we end up dividing by zero when initialising the table. I considered changing the fallback definition of efx_vf_size() to return 1, but its value is really meaningless if we are not going to enable VFs. Therefore add a condition of efx_sriov_wanted(efx) in efx_probe_interrupts(). Signed-off-by: Ben Hutchings --- Reading git-format-patch failed
