Subject: tdc errors

Hi,

When running these 2 tdc tests:

7d64 Add police action with skip_hw option
3329 Validate flags of the matchall filter with skip_sw and
police action with skip_hw
I get this error:

Bad action type skip_hw
Usage: ... gact <ACTION> [RAND] [INDEX]
Where: ACTION := reclassify | drop | continue | pass | pipe |
goto chain <CHAIN_INDEX> | jump <JUMP_COUNT>
RAND := random <RANDTYPE> <ACTION> <VAL>
RANDTYPE := netrand | determ
VAL : = value not exceeding 10000
JUMP_COUNT := Absolute jump from start of action list
INDEX := index value used

I'm building the kernel on net-next.

I'm compiling the latest iproute2 version.

It seems like the problem is that support is lacking for skip_hw
in police action in iproute2.

This is the command that fails in test 7d64:
tc actions add action police rate 1kbit burst 10k index 100 skip_hw

To run this particular test do:
./tdc.py -e 7d64

cheers,
Victor
