Same input/output as [[#Initalize]] except this doesn't take an input handle.

The work-buffer (size is still specified with this cmd) is backed by memory in the sysmodule, instead of TransferMemory. The size (after alignment) must be >=0x1000 and <=0x13F000.

sdknso will only use this cmd when two flags in the input config are set: the first one being set indicates that the bsd:s service is used, while the second flag enables using this cmd. An error is thrown if the work-buffer size is <0x1000. Otherwise when these flags aren't set, [[#Initialize]] is used as usual.

The transfer memory must be larger than a the computed size below. Should the transfer memory be smaller than that, the BSD sockets service would only send ZeroWindow packets (for TCP), resulting in a transfer rate not exceeding 1 byte/s.
