| * lib: Demultiplex the fast pathdimitri staessens2016-10-2127-1145/+1642
| | | | | | | | | | | | | | | | The fast path will now use an incoming ring buffer per flow per process. This necessitated the development of a new method for the asynchronous io call, which is now based on an event queue system for scalability (fqueue). The ipcpd's and tools have been updated to this API.

|/ / | | | | | | | | There was no check to see if the normal IPCP was enrolled or not when a flow allocation request is done.

| | | | | | | | | | | | | | Added the missing implementation of setting read/write options for flows. This allows applications to block the fast path for remotes. IPCPs can use this to block the fast path for the N + 1 flow when receiving remote deallocation requests.

| * ipcpd: normal: Improve upon the internal designSander Vrijders2016-10-1211-574/+411
| | | | | | | | | | | | | | | | This commit will remove the RMT component from the normal IPCP, as some of its functionality would else be duplicated in the FMGR. Now all reading from flows, either N-1 or N+1 is done in the FMGR, then either passed to the FRCT or a lookup is performed in the PFF (not there yet) and the PDU is forwarded.

|/ / | | | | | | | | | | This will allow to finalize deallocating flows until all SDUs have been processed. Read and write calls will now block when a flow was deallocated. Replaces NULL checks in the fast path with asserts.

| |/ |/| | | | | | | | | | | This is the first version of the fast path bootstrap in the normal IPCP. It sets up a connection with the other end, and creates the appropriate data structures. N+1 and N-1 SDUs are read and written and passed through the right components.

| | | | | | | | | | | | | | | | | | | | | | | | IPCPs can now use ap_init() to initialize the memory. All flows are accessed using flow descriptors, this greatly simplifies IPCP development. Reverts the fast path to a single ap_rbuff per process. Splits lib/ipcp into irmd/ipcp and lib/ipcp-dev. Adds a lib/shim-dev holding tailored functions for shims. Moves the buffer_t to utils.h. Fixes the shim-eth-llc length field. Removes the flow from shared.h. Fixes #4 Fixes #5

| | | | | | | | | | | | | | | | | | This adds the operations needed in the normal IPCP to get and set the Protocol Control Information. It allows to allocate or release space in the current DU. The struct pci can be serialized into newly allocate space. Vice versa, a struct pci can be deserialized given a DU. It allows for decreasing the TTL in the DU and for calculating the CRC32. The TTL and CRC32 can now be selected when creating a new DIF.
