I am trying to use tc command in linux to drop udp

I am able set diffserv value successfully in the udp packet
using command:-

[LLVMdev] [PATCH] x86/asm: avoid mnemonics without type suffix
1c54d77 (x86: partial unification of asm-x86/bitops.h, 2008-01-30)
changed a bunch of btrl/btsl instructions to btr/bts, with the following
justification:
The inline assembly for the bit operations has been changed to remove
explicit sizing hints on the instructions, so the assembler will pick
the appropriate instruction forms depending on the architecture and
the context.
Unfortunately,

The Intel documentation implies that this is the case:

[LLVMdev] [BUG] Support unqualified btr, bts
Hi,
I happened to notice that linux.git uses plenty of btr and bts
instructions (not btrl, btrw, btsl, btsw). For examples, see
arch/x86/include/asm/bitops.h. LLVM barfs on these due to ambiguity,
while GNU as is fine with them. Surely, there must be architectures
where the w/l variant is unavailable? LLVM must support those
architectures, no?
Thanks.

[LLVMdev] Issues with inline assembly
Hi guys,
I am trying to compile some files using clang + llvm and I am
encountering the following error during the linking step:
<inline asm>:1:2: error: ambiguous instructions require an explicit
suffix (could be 'btsw', 'btsl', or 'btsq')
bts $14,(%eax)
Which basically does not make any sense, because I don't have the
mentioned inline assembly in any
