io_uring/net: support bundles for recv
If IORING_OP_RECV is used with provided buffers, the caller may also set IORING_RECVSEND_BUNDLE to turn it into a multi-buffer recv. This grabs buffers available and receives into them, posting a single completion for all of it. This can be used with multishot receive as well, or without it. Now that both send and receive support bundles, add a feature flag for it as well. If IORING_FEAT_RECVSEND_BUNDLE is set after registering the ring, then the kernel supports bundles for recv and send. Signed-off-by: Jens Axboe <axboe@kernel.dk>
