From 9329b8162b95200d046b7ef5c9830af9dc74d2ca Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Thu, 13 Dec 2018 11:54:50 +0000 Subject: mlxsw: spectrum: Add mlxsw_sp.mac_mask The Spectrum hardware demands that all router interfaces in the system have the same first 38 resp. 36 bits of MAC address: the former limit holds on Spectrum, the latter on Spectrum-2. Add a field that refers to the required prefix mask and initialize in mlxsw_sp1_init() and mlxsw_sp2_init().
