\| *	ipcpd: shim-eth-llc: Avoid handling mgmt frame under lock	Sander Vrijders	2017-04-06	1	-4/+3
\| \| \| \| \| \| \| \| \| \|	This avoids handling the mgmt frames under lock, since it may deadlock if a new mgmt frame arrives in the meantime.

*	lib, irmd: Implement flow allocation timeout	dimitri staessens	2017-04-06	11	-137/+243
\| \| \| \| \| \|	Setting the timeouts on flow_alloc and flow_accept will now work. This makes some changes to the UNIX sockets used for management communication between the APs, IRMd and IPCPs.
*	ipcpd: shim-eth-llc: Fix overwrite mgmt frames	Sander Vrijders	2017-04-05	1	-21/+42
\| \| \| \| \| \|	This fixes the overwriting of management frames by adding a list in the shim Ethernet that keeps track of management frames instead of a single buffer.
*	ipcpd: normal: Add missing else clause	Sander Vrijders	2017-04-05	2	-10/+7
\| \| \| \| \|	A missing else clause was missing in the fast path, causing the PCI to be shrunk when it should not be. A double free has also been fixed.
*	ipcpd: Add lock for allocation requests	Sander Vrijders	2017-04-05	6	-103/+79
\| \| \| \| \|	This adds a lock to prevent a race condition between flow_req_arr and flow_alloc_resp.
*	ipcpd: shim-eth-llc: Fix state check in reader	Sander Vrijders	2017-04-05	1	-3/+3
\| \| \| \| \|	The state check should be done first to avoid blocking on the recv call.

* \|	ipcpd: shim-eth-llc: Remove IPCP rwlock	Sander Vrijders	2017-04-04	1	-73/+23
\| \| \| \| \| \| \| \| \| \|	This removes the rwlock in the shim-eth-llc IPCP since it is already protected by a mutex.
* \|	ipcpd: shim-eth-llc: Remove pthread_cancel	Sander Vrijders	2017-04-04	1	-78/+117
\| \| \| \| \| \| \| \| \| \|	This removes cancellation calls from the shim Ethernet. The different threads now check if the IPCP is still operational or not.
* \|	ipcpd: shim-eth-llc: Deprecate PACKET_RX\|TX_RING	Sander Vrijders	2017-04-04	1	-203/+11
\| \| \| \| \| \| \| \| \| \| \| \|	This deprecates these special socket options of the raw socket since they are less efficient for regular packet I/O. They should be more performant for batch processing of SDUs.
* \|	ipcpd: shim-eth-llc: Add thread for mgmt frames	Sander Vrijders	2017-04-04	1	-29/+101
\|/ \| \| \| \| \|	This adds a thread to handle management frames, since otherwise a deadlock can occur by blocking SDUs until flow allocation can be handled.

\| *	ipcpd: Revert timeout in fmgr	dimitri staessens	2017-04-01	1	-6/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Since there are no SDUs on most QoS cubes, the fmgr was always timing out on most QoS cubes, causing considerable delays in most SDUs. The timeout was reset to a very small value (so the bug in glibc 2.25 will cause lockups again).

\|/ \| \| \|	This fixes a potential overflow when calculating the packet loss.
*	irmd: Add dynamic threadpool	dimitri staessens	2017-04-01	1	-31/+196
\| \| \| \| \| \| \| \| \| \| \|	This makes the IRMd add/remove worker threads dynamically. IRMD_TPM_TIMEOUT sets a timer in the threadpool manager for checking idle threads. Each time this timer expires, it will reduce the threadpool by one. IRMD_MIN_AV_THREADS is the minimum number of available worker threads. If the number of active threads goes under this threshold, the threadpool manager will create threads to get the number of threads to IRMD_MAX_AV_THREADS, unless IRMD_MAX_THREADS is reached.

\| \| \| \| \| \| \| \| \| \| \| \|	The flow_alloc_res and flow_alloc_resp calls have been removed. The flow_alloc and flow_accept calls are now both blocking and take an additional timeout argument.
