Subject: [PATCH -net-next] net: psample: depends on INET

From: Randy Dunlap <[email protected]>

Fix psample build error when CONFIG_INET is not set/enabled.
PSAMPLE should depend on INET instead of NET since
ip_tunnel_info_opts() is only present for CONFIG_INET.

../net/psample/psample.c: In function ‘__psample_ip_tun_to_nlattr’:
../net/psample/psample.c:216:25: error: implicit declaration of function ‘ip_tunnel_info_opts’; did you mean ‘ip_tunnel_info_opts_set’? [-Werror=implicit-function-declaration]

Or just make this tunnel support optional. psample does not
require it to function correctly.

Thanks.

Sure, I thought of that, but it's not clear to me which bits of it
to make optional, so I'll leave it for its maintainer to handle.

thanks.

The code commit d8bed686ab96169ac80b497d1cbed89300d97f83
adds is optional, so it can be just put into #ifdef's.

Thanks.
