Subject: [PATCH net] net: dsa: bcm_sf2: Configure IMP port for 2Gb/sec
Date: Thu, 16 Jan 2020 12:55:48 -0800
Message-ID: <> (raw)

With the implementation of the system reset controller we lost a setting
that is currently applied by the bootloader and which configures the IMP
port for 2Gb/sec, the default is 1Gb/sec. This is needed given the
number of ports and applications we expect to run so bring back that
