OK, the patch fixed an issue I found when run tdc u32 test.

1..11
not ok 1 afa9 - Add u32 with source match
	Could not match regex pattern. Verify command output:
filter protocol ip pref 1 u32 chain 0 
filter protocol ip pref 1 u32 chain 0 fh 800: ht divisor 1 
filter protocol ip pref 1 u32 chain 0 fh 800::800 order 2048 key ht 800 bkt 0 *flowid 1:1 not_in_hw 
  match 7f000001/ffffffff at 12
	action order 1: gact action pass
	 random type none pass val 0
	 index 1 ref 1 bind 1

After the fix, the u32.json test passed

All test results:

1..11
ok 1 afa9 - Add u32 with source match
ok 2 6aa7 - Add/Replace u32 with source match and invalid indev
ok 3 bc4d - Replace valid u32 with source match and invalid indev
ok 4 648b - Add u32 with custom hash table
ok 5 6658 - Add/Replace u32 with custom hash table and invalid handle
ok 6 9d0a - Replace valid u32 with custom hash table and invalid handle
ok 7 1644 - Add u32 filter that links to a custom hash table
ok 8 74c2 - Add/Replace u32 filter with invalid hash table id
ok 9 1fe6 - Replace valid u32 filter with invalid hash table id
ok 10 0692 - Test u32 sample option, divisor 256
ok 11 2478 - Test u32 sample option, divisor 16


When I post the patch, I though this issue is a clear logic one, so I didn't
 paste the test result.

Thanks
