staging/chunkeey/include/bpf.mk, branch mikrotikStaging tree of Christian Lamparterhttps://git.openwrt.org/openwrt/staging/chunkeey/atom?h=mikrotik2022-01-17T08:14:26Ztreewide: drop use of which2022-01-17T08:14:26ZAnsuel Smith2021-11-25T01:12:58Zurn:sha1:88204bfa82f982a986d2aa3e166a4c5946040308
Ubuntu started to flag which as deprecated and it
seems which is not really standard and may vary
across Distro.
Drop the use of which and use the standard 'command -v'
for this simple task.
Which is still present in the prereq if some package/script
still use which.
A utility script called command_all.sh is implemented that
will just mimic the output of which -a.

bpf-headers: switch to mips64 for 64 bit targets2021-11-19T22:51:20ZFelix Fietkau2021-11-18T21:25:47Zurn:sha1:8f355becdf39e4a166063a887f04f7b4feb78cc0
BTF pointer data has a different size on 32 vs 64 bit targets,
and while the generated eBPF code works, the BTF data fails to validate
on mismatch
