	ping.py has 3 cases, test_v4, test_v6 and test_tcp. But these cases are not executed on the XDP environment. So, it adds XDP environment, existing tests(test_v4, test_v6, and test_tcp) are executed too on the below XDP environment. So, it adds XDP cases. 1. xdp-generic + single-buffer 2. xdp-generic + multi-buffer 3. xdp-native + single-buffer 4. xdp-native + multi-buffer 5. xdp-offload It also makes test_{v4 \| v6 \| tcp} sending large size packets. this may help to check whether multi-buffer is working or not. Note that the physical interface may be down and then up when xdp is attached or detached. This takes some period to activate traffic. So sleep(10) is added if the test interface is the physical interface. netdevsim and veth type interfaces skip sleep.

2025-02-24	selftests: drv-net: test XDP, HDS auto and the ioctl path	Jakub Kicinski
	Test XDP and HDS interaction. While at it add a test for using the IOCTL, as that turned out to be the real culprit. Testing bnxt: # NETIF=eth0 ./ksft-net-drv/drivers/net/hds.py KTAP version 1 1..12 ok 1 hds.get_hds ok 2 hds.get_hds_thresh ok 3 hds.set_hds_disable # SKIP disabling of HDS not supported by the device ok 4 hds.set_hds_enable ok 5 hds.set_hds_thresh_zero ok 6 hds.set_hds_thresh_max ok 7 hds.set_hds_thresh_gt ok 8 hds.set_xdp ok 9 hds.enabled_set_xdp ok 10 hds.ioctl ok 11 hds.ioctl_set_xdp ok 12 hds.ioctl_enabled_set_xdp # Totals: pass:11 fail:0 xfail:0 xpass:0 skip:1 error:0 and netdevsim: # ./ksft-net-drv/drivers/net/hds.py KTAP version 1 1..12 ok 1 hds.get_hds ok 2 hds.get_hds_thresh ok 3 hds.set_hds_disable ok 4 hds.set_hds_enable ok 5 hds.set_hds_thresh_zero ok 6 hds.set_hds_thresh_max ok 7 hds.set_hds_thresh_gt ok 8 hds.set_xdp ok 9 hds.enabled_set_xdp ok 10 hds.ioctl ok 11 hds.ioctl_set_xdp ok 12 hds.ioctl_enabled_set_xdp # Totals: pass:12 fail:0 xfail:0 xpass:0 skip:0 error:0 Netdevsim needs a sane default for tx/rx ring size. ethtool 6.11 is needed for the --disable-netlink option.
