When running in a single TC mode the HW can be configured to enable more than max RSS qps for the Main VSI. This patch makes it possible to enable as many as num_online_cpus(). ethtool -L can still be used to reconfigure number of qps to a smaller value.

Since we now have functionality to enable and disable PF loopback at runtime, don't try to do it automatically. Removing this call also gets rid of a bogus error message when removing the PF module with VFs enabled. Change-ID: Ic38652d8a3b9498d96113bfaa5ea7bad050862e9 Signed-off-by:

Include the FW build number in the formatted FW version string. In order to fit within ethtool's 32 character limit, the etrack's unused high order bits are trimmed as is the leading 0 for the NVM version. This leaves us with 2 character left for if/when the etrack id goes to 5 hex chars and the NVM major number goes to 2 chars. Change-ID: Icb004c4b9b14a2f54dd200b467fcc1d7b9297308 Signed-off-by:

Matthew Vick authored
The FM10000 host interface can only support up to 184 bytes when performing tunnel offloads. Because of this, a check was added to prevent the driver from attempting to feed a header to the hardware too big for it to parse. Make this check a little more robust by calculating the inner L4 header length based on whether it is TCP or UDP. Cc: Joe Stringer <joestringer@nicira.com> Signed-off-by:

Eric W. Biederman says: ==================== Neighbour table and ax25 cleanups While looking at the neighbour table to what it would take to allow using next hops in a different address family than the current packets I found a partial resolution for my issues and I stumbled upon some work that makes the neighbour table code easier to understand and maintain. Long ago in a much younger kernel ax25 found a hack to use dev_rebuild_header to transmit it's packets instead of going through what today is ndo_start_xmit. When the neighbour table was rewritten into it's current form the ax25 code was such a challenge that arp_broken_ops appeard in arp.c and neigh_compat_output appeared in neighbour.c to keep the ax25 hack alive. With a little bit of work I was able to remove some of the hack that is the ax25 transmit path for ip packets and to isolate what remains into a slightly more readable piece of code in ax25_ip.c. Removing the need for the generic code to worry about ax25 special cases. After cleaning up the old ax25 hacks I also performed a little bit of work on neigh_resolve_output to remove the need for a dst entry and to ensure cached headers get a deterministic protocol value in their cached header. This guarantees that a cached header will not be different depending on which protocol of packet is transmitted, and it allows packets to be transmitted that don't have a dst entry. There remains a small amount of code that takes advantage of when packets have a dst entry but that is something different. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Having a dst helps a little bit for teql but is fundamentally unnecessary and there are code paths where a dst is not available that it would be nice to use the neighbour cache. Signed-off-by:

Have ax25_neigh_output perform ordinary arp resolution before calling ax25_neigh_xmit. Call dev_hard_header in ax25_neigh_output with a destination address so it will not fail, and the destination mac address will not need to be set in ax25_neigh_xmit. Remove arp_find from ax25_neigh_xmit (the ordinary arp resolution added to ax25_neigh_output removes the need for calling arp_find). Document how close ax25_neigh_output is to neigh_resolve_output.

AX25 already has it's own private arp cache operations to isolate it's abuse of dev_rebuild_header to transmit packets. Add a function ax25_neigh_construct that will allow all of the ax25 devices to force using these operations, so that the generic arp code does not need to.

Not setting the destination address is a bug that I suspect causes no problems today, as only the arp code seems to call dev_hard_header and the description I have of rose is that it is expected to be used with a static neigbour table. I have derived the offset and the length of the rose destination address from rose_rebuild_header where arp_find calls neigh_ha_snapshot to set the destination address.

Patrick is preparing a large batch to enhance the set infrastructure, named expressions among other things, that should follow up soon after this batch. ==================== Signed-off-by: -

Ying Xue says: ==================== net: Remove iocb argument from sendmsg and recvmsg Currently there is only one user - TIPC whose sendmsg() instances using iocb argument. Meanwhile, there is no user using iocb argument in its recvmsg() instance. Therefore, if we eliminate the werid usage of iobc argument from TIPC, the iocb argument can be removed from all sendmsg() and recvmsg() instances of the whole networking stack.

After TIPC doesn't depend on iocb argument in its internal implementations of sendmsg() and recvmsg() hooks defined in proto structure, no any user is using iocb argument in them at all now. Then we can drop the redundant iocb argument completely from kinds of implementations of both sendmsg() and recvmsg() in the entire networking stack. Cc: Christoph Hellwig <hch@lst.de> Suggested-by:

Currently the iocb argument is used to idenfiy whether or not socket lock is hold before tipc_sendmsg()/tipc_send_stream() is called. But this usage prevents iocb argument from being dropped through sendmsg() at socket common layer. Therefore, in the commit we introduce two new functions called __tipc_sendmsg() and __tipc_send_stream(). When they are invoked, it assumes that their callers have taken socket lock, thereby avoiding the weird usage of iocb argument.

Eyal Birger says: ==================== net: move skb->dropcount to skb->cb[] Commit 97775007 ("af_packet: add interframe drop cmsg (v6)") unionized skb->mark and skb->dropcount in order to allow recording of the socket drop count while maintaining struct sk_buff size. skb->dropcount was introduced since there was no available room in skb->cb[] in packet sockets. However, its introduction led to the inability to export skb->mark to userspace. It was considered to alias skb->priority instead of skb->mark. However, that would lead to the inabilty to export skb->priority to userspace if desired. Such change may also lead to hard-to-find issues as skb->priority is assumed to be alias free, and, as noted by Shmulik Ladkani, is not 'naturally orthogonal' with other skb fields. This patch series follows the suggestions made by Eric Dumazet moving the dropcount metric to skb->cb[], eliminating this problem at the expense of 4 bytes less in skb->cb[] for protocol families using it. The patch series include compactization of bluetooth and packet use of skb->cb[] as well as the infrastructure for placing dropcount in skb->cb[]. ==================== Signed-off-by:

Commit 3b885787 ("net: Generalize socket rx gap / receive queue overflow cmsg") allowed receiving packet dropcount information as a socket level option. RXRPC sockets recvmsg function was changed to support this by calling sock_recv_ts_and_drops() instead of sock_recv_timestamp(). However, protocol families wishing to receive dropcount should call sock_queue_rcv_skb() or set the dropcount specifically (as done in packet_rcv()). This was not done for rxrpc and thus this feature never worked on these sockets. Formalizing this by not calling sock_recv_ts_and_drops() in rxrpc as part of an effort to move skb->dropcount into skb->cb[] Signed-off-by:
