Subject: scripts: sercomm-pid: add bmips support
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0cdc257b8d371e85133b7f463785785fe5f0aee3;p=openwrt%2Fstaging%2Fblocktrron.git

scripts: sercomm-pid: add bmips support

Apparently, Sercomm sets 2 padding bytes instead of 1 (ramips).
The HW version is a bit different than the one used for ramips.
