Subject: qualcommax: make header length configurable on Build/mstc-header
X-Git-Url: http://git.openwrt.org/%22https:/collectd.org//%22%24PHP_SELF/%22https:/collectd.org/%22%24PHP_SELF?a=commitdiff_plain;h=2186f4aa757d63f22cdd6cb3b02d09d15848b1f6;p=openwrt%2Fopenwrt.git

qualcommax: make header length configurable on Build/mstc-header

I-O DATA WN-DAX3000GR has a MSTC (Mitra Star Technology Corp.) specific
header with a different length than ELECOM WRC-X3000GS2.
Make the header length configurable by parameterizing on
Build/mstc-header.

- WRC-X3000GS2: 0x400
- WN-DAX3000GR: 0x480
