PACKET_TX_TIMESTAMP is defined in if_packet.h but it is not included in
test. But we cannot include it because we have definitions of struct and
including leads to redefinition error. So define PACKET_TX_TIMESTAMP too.

The conflicts are with <netpacket/packet.h>. I think it will build if
you remove that.

This commit only moved the file. The file was moved twice. Even though
it cannot really be applied easily before the move, this goes back to
commit 8fe2f761cae9 ("net-timestamp: expand documentation").

Do you also get the compiler warning about ambiguous control flow?
tools/testing/selftests/net/txtimestamp.c:498:6: warning: suggest
explicit braces to avoid ambiguous ‘else’ [-Wdangling-else]
When touching this file, might be good to also fix that up:
- if (cfg_use_pf_packet || cfg_ipproto == IPPROTO_RAW)
+ if (cfg_use_pf_packet || cfg_ipproto == IPPROTO_RAW) {
if (family == PF_INET)
total_len += sizeof(struct iphdr);
else
total_len += sizeof(struct ipv6hdr);
+ }

Good point. I will try to replace the includes.

Yeah, you are right. Didn't go so deep.

Yes, but skipped it because the main goal was to fix selftests/net build in
general and forgot about it later. I will address this warning too.
Thanks Willem!
