| Subject: [PATCH] net: dsa: bcm_sf2: Configure IMP port for 2Gb/sec |
| |
| commit 8f1880cbe8d0d49ebb7e9ae409b3b96676e5aa97 upstream. |
| |
| 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 |
| setting. |
| |
