    Thank you for merging! I prepared kernel with AF_XDP enabled and my test application works fine: sock0@wan:0 rxdrop pps pkts 1.00 rx 9,310 9,323 tx 0 0 Packet rate aren't impressive but my packet generator works over WIFI and Powerline. I do not expect performance here That's great place for future improvements!

    I created PR to enable this feature: https://github.com/armbian/build/pull/1146

    Well, I noticed one issues with this kernel. Any chance to enable kernel configuration option CONFIG_XDP_SOCKETS in kernel for EspressoBin? We participated in testing this feature when it was in bpf-next and it worked fine on our ARM64 machines (Thunder X machines from Cavium). I expect that it should work on EspressoBin fine too. I tried test app for AF_XDP and it does not work: libbpf: failed to create map (name: 'xsks_map'): Invalid argument libbpf: failed to load object './xdpsock_user_kern.o' And dump from strace: 2909 bpf(BPF_MAP_CREATE, {map_type=BPF_MAP_TYPE_ARRAY, key_size=4, value_size=4 , max_entries=1, map_flags=0, inner_map_fd=0, ...}, 72) = 3 2909 bpf(BPF_MAP_CREATE, {map_type=0x11 /* BPF_MAP_TYPE_??? */, key_size=4, val ue_size=4, max_entries=4, map_flags=0, inner_map_fd=0, ...}, 72) = -1 EINVAL (In valid argument) 2909 write(2, "libbpf: failed to create map (name: 'xsks_map'): Invalid argumen t\n", 66) = 66 2909 close(3) = 0 2909 write(2, "libbpf: failed to load object './xdpsock_user_kern.o'\n", 54) = 54 It offers significantly improved logic for network processing and will be useful for network targeted boards like this. Thank you!

    Hello! Thank you for porting Ubuntu 18.04 to EspressoBin! It works great I noticed only small issues with systremd: [FAILED] Failed to start Wait for Network to be Configured. See 'systemctl status systemd-networkd-wait-online.service' for details.

    Hello! Any plans about 4.17? I just booted my ARM64 Cavium Thunder with this kernel and it was quite challenging But this kernel has number of nice additions for ARM boards!

Looks like network card has some issues with checksum offload. What is the best way to report this issue to Marvell?

    Looking for an enclosure for espressobin

    Hello! Do you have any progress with this box? I’m looking for box for EspressoBin and would buy some of you can sell them

    Also, I noticed significant amount of "do_csum.part.0" in perf top output and hardware checksum offload does not work on mvneta: ethtool -K eth0 rx on Cannot get device udp-fragmentation-offload settings: Operation not supported Cannot change rx-checksumming Cannot get device udp-fragmentation-offload settings: Operation not supported Could not change any device features I collected this output with about 8Mbits of incoming UDP traffic. Also, this patch https://github.com/torvalds/linux/commit/ca5902a6547f662419689ca28b3c29a772446caa#diff-851bfc43b3ca32355b4c07d29dbba7f0 can offer some nice benefits and spread traffic processing to multiple queues.

    Looks like 4.16 kernel has number of nice features for EspressoBin (cpu scaling, crypto). Do you have any plans to offer builds on this kernel?

    Just installed Ubuntu 16.04 with 4.14.38-mvebu64. It works REALLY great! Thank you so much for your effort!
