From 1f4522400e7e49464da5e584a463bd315283790f Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Thu, 11 Feb 2016 12:28:55 -0200 Subject: [media] [for,v4.5] media.h: increase the spacing between function ranges Each function range is quite narrow and especially for connectors this will pose a problem. Increase the function ranges while we still can and move the connector range to the end so that range is practically limitless.

As a result, the stack dropped ingress vxlan IPv6 packets, that have been sent via eBPF through collect meta data mode due to checksum now being zero. Since after LCO, we enable IPv4 checksum by default, so make that analogous and only provide a flag BPF_F_ZERO_CSUM_TX for the user to turn it off in IPv4 case.

The arguments themselves do not need to be aligned to a power of two, but aligning them up to the largest basic type alignment (u64) on common ABIs is a good thing to do. The patch changes the size of the reserved fields to 5 or 6 u32's and aligns the size of the struct to 8 bytes so we do no longer depend on the compiler to perform the alignment. While at it, add __attribute__ ((packed)) to these structs as well.
