Drivers use different fields to report the number of channels, so take the maximum of all data channels (rx, tx, combined) when determining the size of the xsk map. The current code used only 'combined' which was set to 0 in some drivers e.g. mlx4. Tested: compiled and run xdpsock -q 3 -r -S on mlx4 Signed-off-by: Luigi Rizzo <lrizzo@google.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Reviewed-by: Jakub Kicinski <jakub.kicinski@netronome.com> Acked-by: Magnus Karlsson <magnus.karlsson@intel.com> Link: https://lore.kernel.org/bpf/20191119001951.92930-1-lrizzo@google.com |
