| * usrp1: use the transport frame sizes to calculate the max sppJosh Blum2010-10-062-80/+99
| | | | | | | | | | | | | | | | | | The max send spp is the frame size minus the alignment padding. This allows us to copy a remainder into a new buffer and always commit multiples of the alignment size (512 bytes). Reworked the managed send buffer implementation to handle the above. Uses only managed memory, and only mem-copied under the alignment.

| * | uhd: reworked the zero copy interfaceJosh Blum2010-10-026-325/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - recv buffers have a release call - safe make function for recv buffers (buff + release callback) - send buffer commits now have a void return - safe make function for send buffers (buff + commit callback) The reason for the void return from commit is that ssize_t num_bytes was never returning anything of use. That is for all of the zero copy implementations so far, commit cannot really error (being asynchronous). libusb zero copy impl was reworked to support the new interface. USRP1 io_impl with the psuedo managed buffer was replaced with safe_make. Also, usrp1 io_impl was simplified greatly due to commit returning void now. UDP zero copy asio was disabled (in this commit, until its reworked). Phony send and recv interfaces were removed completely.
