This fixes compilation failures related to START_TIMER/STOP_TIMER macros and
-Werror=declaration-after-statement.  START_TIMER declares variables and thus
may not be placed after statements outside of a new block.

Make use of the experimental framesize enumeration ioctl if available.

Unbreak direct streamcopy.

Check capabilities directly in the function, further simplify the code.
