This reverts commit c8c590f07ad7ffaa6ef11e90b81202212077497b which is commit 90a695c3d31e1c9f0adb8c4c80028ed4ea7ed5ab upstream.

Commit c8c590f07ad7 ("selftests/bpf: Implement get_hw_ring_size function to retrieve current and max interface size") will cause the following bpf selftests compilation error in the 6.6 stable branch, and it is not the Stable-dep-of of commit 103c0431c7fb ("selftests/bpf: Drop unneeded error.h includes"). So let's revert commit c8c590f07ad7 to fix this compilation error.

./network_helpers.h:66:43: error: 'struct ethtool_ringparam' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] 66 | int get_hw_ring_size(char *ifname, struct ethtool_ringparam *ring_param);
