- Subject: ar71xx: fix wndr3700_board_detect for some NETGEAR WNDR3700v2
- There are a few NETGEAR devices which don't terminate the model name in the
- ART with a NUL byte, at least some NETGEAR WNDR3700v2. The current awk
- expression doesn't match 0xFF bytes, so AR71XX_MODEL contains lots of
- trailing 0xFF garbage in this case.
- Fix this by matching for the first non-printable character and explicitly
- setting LC_CTYPE=C (probably not strictly necessary on OpenWrt, but will
- definitely work like this, even when awk supports locales and LANG is set).
