[SRU][F/B][PATCH 0/1] gtp: add GTPA_LINK info to msg sent to userspace

SRU Justification


When a user dump pdp contextes, it cannot associate them with existing
gtp interfaces. Thus, the dump is unusable.

This problem has been fixed in the upstream commit b274e47d9e3f ("gtp:
add GTPA_LINK info to msg sent to userspace"):

[Test Case]

Create several gtp interfaces and setup PDP contextes on them. Perform a
dump with the genl command GTP_CMD_GETPDP.

[Regression Potential]

The patch affects only the gtp driver and is quite trivial. Thus, the
potential regressions are limited to this area and low.


This fix is queued for all the stable trees so we'll get this fix sooner
or later; but because it's a one liner fix, we might as well SRU to get
this sooner.
