*	ipcpd: Add ethertype check	Dimitri Staessens	2018-04-05	1	-1/+7
\| \| \| \| \| \| \| \|	An ethertype check was missing for the DIX ethernet IPCP, causing crashes if there is other traffic on the network. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
*	ipcpd: Avoid unnecessary copy in eth writer	Dimitri Staessens	2018-04-05	1	-25/+45
\| \| \| \| \| \| \| \| \|	This writes into the Ethernet device directly from the rdrbuff to avoid a copy on the write side in the Ethernet IPCPs. This does not work for the netmap device.

*	ipcpd: Avoid unnecessary copy in eth reader	Dimitri Staessens	2018-04-05	1	-31/+70
\| \| \| \| \| \| \| \| \|	This reads from the Ethernet device directly into the rdrbuff to avoid a copy on the read side in the Ethernet IPCPs. This does not work for the netmap device.

*	ipcpd: Enable locking threads to a CPU core	Dimitri Staessens	2018-04-05	1	-0/+4
\| \| \| \| \| \| \| \| \|	This adds a function that locks a thread to a random core. This greatly improves performance on multi-cpu systems. There is no portable way to do this, this only implements it for GNU/Linux. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
*	ipcpd: Fix frame buffer in eth ipcps	Dimitri Staessens	2018-04-05	1	-2/+2
\| \| \| \| \| \| \| \|	The packets were being sent and read into a buffer that had the payload length instead of the frame length. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
*	ipcpd: Add validity checks for eth-dix	Dimitri Staessens	2018-03-12	1	-0/+4
\| \| \| \| \| \| \| \|	This will check if the Ethertype value is a valid Ethertype in the irm tool and the eth-dix IPCPd. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
*	ipcpd: Add length field to eth-dix	Dimitri Staessens	2018-03-10	1	-62/+57
\| \| \| \| \| \| \| \| \|	Some NICs added padding to the Ethernet II frames causing bad frame lengths and GPB unpack fails. This adds a 2-byte length field to the DIX frame to circumvent this.

*	ipcpd: Add IPCP over DIX Ethernet	Dimitri Staessens	2018-03-10	4	-0/+1811
	This adds an IPC Process that uses DIX Ethernet with an Ethertype that is configurable at bootstrap. This allows parallel DIX layers over the same Ethernet network with different Ethertypes (and one LLC layer). It allows jumbo frames in the future, and should avoid the problems we have with some routers not handling LLC traffic very well. The destination endpoint ID is sent as a 16 bit integer, so the maximum payload is 1498 bytes in standard Ethernet, and 8998 bytes when Jumbo frames are used. The implementation is very similar to the Ethernet LLC IPCP, so it is implemented using preprocessor macros in the single source instead of duplicating code.
