[PATCH] Fix check if device is ethernet in alloc_divert_blk

Hello,

I was wondering why various devices like 802.11 bridges and tap devices
weren't recognized by the kernel as ethernet devices, because I got
messages like this in my syslog:

Oct 30 15:35:52 haplo kernel: divert: not allocating divert_blk for non-ethernet device bla

Instead of checking for the actual device type, alloc_divert_blk was
just checking if the string "eth" occured in the name of the interface.
Attached patch makes it do the right thing instead (I hope).
