This support requires a number of changes, some **breaking to the bcc APIs**.\r\n\r\nChanges to the Python methods `load_func` and `BPF` are backward-compatible. Changes to `bpf_module_create_b`, `bpf_module_create_c`, `bpf_module_create_c_from_string`, and `bcc_func_load`, and `BPFModule::BPFModule` are not. I'm not sure which of these we want to avoid or there's a better way; I'm opening this pull request to start the discussion.\r\n\r\nI've also updated the `xdp_drop_count.py` example to support hardware offload with the new `-H device` option.ghprbCommentBodynullghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="Support for hardware offload" href="https://github.com/iovisor/bcc/pull/2502">PR #2502</a>: Support for hardware offload#6010580397460664bcc-pr #6060false60508SUCCESS1567438685788https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/60/git60https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc25/60/60https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc26/60/60https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc27/60/60https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc28/60/60https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=ubuntu1604/60/60https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=ubuntu1710/60/60https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=ubuntu1804/60/
