Subject: Re: [bpf-next PATCH] bpf: Add rx_queue_mapping to bpf_sock
Hi Amritha,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on bpf-next/master]
[also build test ERROR on bpf/master net/master net-next/master v5.7-rc6 next-20200521]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
