xdp_tstamp.c currectly hardcodes the XSKMAP size to 4, but it redirects to XSKs based on ctx->rx_queue_index. We can look up the number of queues with an ethtool ioctl and resize the XSKMAP before loading the map into the kernel. The non-xdp_tstamp path works fine because xdp_map_create in efhw/af_xdp.c creates max_entries = nic->vi_lim. Signed-off-by: YiFei Zhu <zhuyifei@google.com>
