Crack open GRE packets in __skb_get_rxhash to compute 4-tuple hash on in encapsulated packet. Note that this is used only when the __skb_get_rxhash is taken, in particular only when the device does not compute provide the rxhash (ie. feature is disabled). This was tested by creating a single GRE tunnel between two 16 core AMD machines. 200 netperf TCP_RR streams were ran with 1 byte request and response size.

The l4_rxhash flag was added to the skb structure to indicate that the rxhash value was computed over the 4 tuple for the packet which includes the port information in the encapsulated transport packet. This is used by the stack to preserve the rxhash value in __skb_rx_tunnel. Signed-off-by: NTom Herbert <therbert@google.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Ben Hutchings 提交于
The current descriptions state that these fields specify 'How many packets to delay ... after a packet ...' which implies that the hardware should wait for (max_coalesced_frames + 1) completions before generating an interrupt. It is also stated that setting both this field and the corresponding 'coalesce_usecs' field to 0 is invalid. Together, this implies that the hardware must always be configured to delay a completion IRQ for at least 1 usec or 1 more completion. I believe that the addition of 1 is not intended, and David Miller confirms that the original implementation (in tg3) does not do this. Clarify the descriptions of these fields to avoid this interpretation. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch extends the HiperSockets device driver to send and receive af_iucv traffic over HiperSockets transport. TX: Driver uses new asynchronous delivery of storage blocks to pass flow control/congestion information from the HiperSockets microcode to the af_iucv socket. RX: Memory for incoming traffic is preallocated and passed to HiperSockets layer. If receiver is not capable to clean its buffers shared with HiperSockets and pass new memory to the HiperSockets layer this will cause flow control/congestion events on the sender.

The current transport mechanism for af_iucv is the z/VM offered communications facility IUCV. To provide equivalent support when running Linux in an LPAR, HiperSockets transport is added to the AF_IUCV address family. It requires explicit binding of an AF_IUCV socket to a HiperSockets device. A new packet_type ETH_P_AF_IUCV is announced. An af_iucv specific transport header is defined preceding the skb data. A small protocol is implemented for connecting and for flow control/congestion management.

After the move of the Ethernet drivers into drivers/net/ethernet/ there was some leftover cleanup to do in the Kconfig and Makefile. Removed the 10/100, 1000, and 10GbE Kconfig menus. Removed the out-dated pci-skeleton.c file which was used an example driver. With the current networking features and structure, the file is no longer a good example to use for driver creation.
