Subject: mlxsw: reg: Add mlxsw_reg_ralue_act_ip2me_tun_pack()
Patch-mainline: v4.14-rc1
Git-commit: a43da820c8ff671054105144287766a24cfbcdc0
References: bsc#1112374

To implement IP-in-IP decapsulation, Spectrum uses LPM entries of type
IP2ME with tunnel validity bit and tunnel pointer set. The necessary
register fields are already available, so add a function to pack the
RALUE as appropriate.
