Re: [PATCH 0/3] Zero-copy L2CAP ERTM & streaming reassembly

Hi Mat,

This patch series changes SDU reassembly to link together PDU skbs
using a frag list instead of copying all data bytes to a single,
linear skb.  The reduction in overhead is especially helpful with high
speed AMP links.
I have not looked at these at all, but one thing that came up in a
discussion between Johan and myself with OBEX zero-copy was that we like
to also see MSG_MORE support for L2CAP and RFCOMM sockets. Something to
keep in mind ;)
Noted!  It would be nice to build up OBEX packets in the kernel, 
rather than having to assemble entire packets in an application 
buffer.
hence the request for MSG_MORE support. That would allow us to build
frames properly. Could also become a pretty nice enhancement for A2DP.

Regards

Marcel
