The mail box containing the Vf-Pf messages is susceptible to a race - it's possible for 2 flows to try and write commands, causing one to override the other's message.

This patch enhances the stmmac driver to support IEEE 1588-2002 PTP (Precision Time Protocol) version 1 and IEEE 1588-2008 PPT version 2. Precision Time Protocol(PTP),which enables precise synchronization of clocks in measurement and control systems implemented with technologies such as network communication,local computing, & distributed objects. Both PTPv1 and PTPv2 is selected at run-time using the HW capability register. The PTPv1 TimeStamp support can be used on chips that have the normal descriptor structures and PTPv2 TimeStamp support can be used on chips that have the Extended descriptors(DES4-5-6-7). All such sanity checks are done and verified by using HW capability register. V2: in this version the ethtool support has been included in this patch; Koptions have been completely removed (previously added to select PTP and PTPv2). PTPv1 and PTPv2 is now added in a single patch instead of two patches. get_timestamp() and get_systemtime() L/H have been combined into single APIs.

This patch adds a new pointer variable called "tx_skbuff_dma" to private data structure. This variable will holds the physical address of packet to be transmitted & same will be used to free/unmap the memory once the corresponding packet is transmitted by device. Prior to this patch the descriptor buffer pointer(ie des2) itself was being used for freeing/unmapping the buffer memory. But in case PTP v1 with normal descriptor the field(des2) will be overwritten by device with timestamp value, hence driver will loose the buffer pointer to be freed/unmapped.

This patch is to support the extend descriptors available in the chips newer than the 3.50. In case of the extend descriptors cannot be supported, at runtime, the driver will continue to work using the old style. In detail, this support extends the main descriptor structure adding new descriptors: 4, 5, 6, 7. The desc4 gives us extra information about the received ethernet payload when it is carrying PTP packets or TCP/UDP/ICMP over IP packets. The descriptors 6 and 7 are used for saving HW L/H timestamps (PTP). V2: this new version removes the Koption added in the first implementation because all the checks now to verify if the extended descriptors are actually supported happen at probe time.

Previously we had two Koptions to decide if the stmmac had to use either a ring or a chain to manage its descriptors. This patch removes the Kernel configuration options and it allow us to use the chain mode by passing a module option. Ring mode continues to be the default. Also with this patch, it will be easier to validate the driver built and guarantee that all the two modes always compile fine.

Currently, for the packets receives from netback, before doing header check, kernel just reset the transport header in netif_receive_skb() which pretends non l4 header. This is suboptimal for precise packet length estimation (introduced in 1def9238: net_sched: more precise pkt_len computation) which needs correct l4 header for gso packets. The patch just reuse the header probed by netback for partial checksum packets and tries to use skb_flow_dissect() for other cases, if both fail, just pretend no l4 header.

This is suboptimal for precise packet length estimation (introduced in 1def9238) which needs correct l4 header for gso packets. So this patch set the transport header to csum_start for partial checksum packets, otherwise it first try skb_flow_dissect(), if it fails, just reset the transport header.

Following patch refactors GRE code into ip tunneling code and GRE specific code. Common tunneling code is moved to ip_tunnel module. ip_tunnel module is written as generic library which can be used by different tunneling implementations. ip_tunnel module contains following components: - packet xmit and rcv generic code. xmit flow looks like (gre_xmit/ipip_xmit)->ip_tunnel_xmit->ip_local_out. - hash table of all devices. - lookup for tunnel devices. - control plane operations like device create, destroy, ioctl, netlink operations code. - registration for tunneling modules, like gre, ipip etc. - define single pcpu_tstats dev->tstats. - struct tnl_ptk_info added to pass parsed tunnel packet parameters. ipip.h header is renamed to ip_tunnel.h Signed-off-by: NPravin B Shelar <pshelar@nicira.com> Signed-off-by: NDavid S.
