Description

http://php.net/manual/en/function.is-numeric.php

7.0.0 Strings in hexadecimal (e.g. 0xf4c3b00c) notation are no longer regarded as numeric strings, i.e. is_numeric() returns FALSE now.

Best fix appears to be using http://php.net/manual/en/function.ctype-xdigit.php without prepending 0x to the string.

The only uses of this for hexadecimal that I can find is interfaces.php and handling of the track6 prefix ID, but worth checking for other instances.
