6431cbc2(Create a mechanism for upward inetpeer propagation into routes) introduces these codes, but this mechanism is never enabled since rt6i_peer_genid always is zero whether it is not assigned or assigned by rt6_peer_genid(). After 5943634f (ipv4: Maintain redirect and PMTU info in struct rtable again), the ipv4 related codes of this mechanism has been removed, I think we maybe able to remove them now.

Included changes: - minimal fixes to the packet layout to avoid the __packed attribute when not needed - new packet type called UNICAST_4ADDR: in this packet it is possible to find both source and destination node (in the classic UNICAST header only the destination field exists). - a new feature: Distributed ARP Table (D.A.T.). It aims to reduce ARP lookups latency by means of a simil-DHT approach.

This patch replaces the BCM_CNIC define with a flag which can change at run-time and which does not use the CONFIG_CNIC kconfig option. For the PF/hypervisor driver cnic is always supported, however allocation of cnic resources and configuration of the HW for offload mode is done only when the cnic module registers bnx2x.

This patch updates the driver-FW HSI to support changes to the 'update' ramrod (FW supports this change since 7.8.2). This ramrod is sent when the cnic module registers bnx2x, to enable changing the nic_mode configuration in HW at run-time.

The tx data offset of packet mmap tx ring used to be : (TPACKET2_HDRLEN - sizeof(struct sockaddr_ll)) The problem is that, with SOCK_RAW socket, the payload (14 bytes after the beginning of the user data) is misaligned. This patch allows to let the user gives an offset for it's tx data if he desires. Set sock option PACKET_TX_HAS_OFF to 1, then specify in each frame of your tx ring tp_net for SOCK_DGRAM, or tp_mac for SOCK_RAW.

The macb driver in u-boot uses the first register set while the at91_ether driver in u-boot uses the second register set. By checking all register set, like at91_ether does, this code can be shared between the drivers. This only changes behavior on macb if no vaild address is found in the first register set.

mlx4 currently uses a too high tx coalescing setting, deferring TX completion interrupts by up to 128 us. With the recent skb_orphan() removal in commit 8112ec3b, performance of a single TCP flow is capped to ~4 Gbps, unless we increase tcp_limit_output_bytes. I suggest using 16 us instead of 128 us, allowing a finer control. Performance of a single TCP flow is restored to previous levels, while keeping TCP small queues fully enabled with default sysctl. This patch is also a BQL prereq.

The "early client detection mechanism" can be extended to find new clients by means of unicast_4addr packets. The unicast_4addr packet contains as well as the broadcast packet (which is currently used in this mechanism) the address of the originating node and can therefore be used to install new entries in the Global Translation Table Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>

In case of an ARP message going in or out the soft_iface, it is intercepted and a special action is performed. In particular the DHT helper functions previously implemented are used to store all the ARP entries belonging to the network in order to provide a fast and unicast lookup instead of the classic broadcast flooding mechanism. Each node stores the entries it is responsible for (following the DHT rules) in its soft_iface ARP table. This makes it possible to reuse the kernel data structures and functions for ARP management.

The current unicast packet type does not contain the orig source address. This patches add a new unicast packet (called UNICAST_4ADDR) which provides two new fields: the originator source address and the subtype (the type of the data contained in the packet payload). The former is useful to identify the node which injected the packet into the network and the latter is useful to avoid creating new unicast packet types in the future: a macro defining a new subtype will be enough.

Headers which are already perfectly aligned and create a 4 byte boundary non-ethernet header payload can have the __packed attribute removed. The __packed attribute doesn't change the appeareance of the packet for these headers because no extra padding is necessary to align the data members. The compiler will also create slightly faster code for loads of multi-byte members.
