[ Upstream commit 1cd9b3abf5332102d4d967555e7ed861a75094bf ]
In net/Kconfig, NET_DEVLINK implies NET_DROP_MONITOR.
The original behavior of the 'imply' keyword prevents NET_DROP_MONITOR
from being 'm' when NET_DEVLINK=y.
With the planned Kconfig change that relaxes the 'imply', the
combination of NET_DEVLINK=y and NET_DROP_MONITOR=m would be allowed.
Use IS_REACHABLE() to avoid the vmlinux link error for this case.

drop_monitor: Add basic infrastructure for hardware drops2019-08-17T19:40:08+00:00Ido Schimmelidosch@mellanox.com2019-08-17T13:28:12+00:00urn:sha1:edd3d0074c256848bbf5805350b39d40b1e2bf2b
Export a function that can be invoked in order to report packets that
were dropped by the underlying hardware along with metadata.
Subsequent patches will add support for the different alert modes.
