the icmp and the icmp_rr packets share the same initial fields since they use the same code to be processed and forwarded. Extract the common fields and put them into a separate struct so that future ICMP packets can be easily added without bloating the packet definition. However, keep the seqno field outside of the newly created common header because future ICMP types may require a bigger sequence number space. This change breaks compatibility due to fields reordering in the ICMP headers. Signed-off-by: NAntonio Quartulli <antonio@open-mesh.com> Signed-off-by: NMarek Lindner <lindner_marek@yahoo.de>

When comparing a network ordered value with a constant, it is better to convert the constant at compile time by means of htons() instead of converting the value at runtime using ntohs().

In case of a VLAN tagged frame the ethhdr pointer is moved forward by 4 bytes so that the offset of h_proto in struct ethhdr matches the real h_vlan_encapsulated_proto address in the skb.

In commit 634fb979 ("inet: includes a sock_common in request_sock") I forgot that the two ports in sock_common do not have same byte order : skc_dport is __be16 (network order), but skc_num is __u16 (host order) So sparse complains because ir_loc_port (mapped into skc_num) is considered as __u16 while it should be __be16 Let rename ir_loc_port to ireq->ir_num (analogy with inet->inet_num), and perform appropriate htons/ntohs conversions.

Allocate the queue pairs individually instead of as a group. This allows for much easier queue management as it is possible to dynamically resize the queues without having to free and allocate the entire block. Ease statistic collection by treating Tx/Rx queue pairs as a single unit. Each pair is allocated together and starts with a Tx queue and ends with an Rx queue. By ordering them this way it is possible to know the Rx offset based on a pointer to the Tx queue.

This makes it so that the Tx and Rx byte and packet counts are separated from the rest of the statistics. This allows for better isolation of these stats when we move them into the 64 bit statistics. Simplify things by re-ordering how the stats display in ethtool. Instead of displaying all of the Tx queues as a block, followed by all the Rx queues, the new order is Tx[0], Rx[0], Tx[1], Rx[1], ..., Tx[n], Rx[n]. This reduces the loops and cleans up the display for testing purposes since it is very easy to verify if flow director is doing the right thing as the Tx and Rx queue pair are shown in pairs.

Avoid directly incrementing next_to_use for multiple reasons. The main reason being that if we directly increment it then it can attain a state where it is equal to the ring count. Technically this is a state it should not be able to reach but the way this is written it now can. This patch pulls the value off into a register and then increments it and writes back either the value or 0 depending on if the value is equal to the ring count.

skb_gro_receive() is currently limited to 16 or 17 MSS per GRO skb, typically 24616 bytes, because it fills up to MAX_SKB_FRAGS frags. It's relatively easy to extend the skb using frag_list to allow more frags to be appended into the last sk_buff. This still builds very efficient skbs, and allows reaching 45 MSS per skb. (45 MSS GRO packet uses one skb plus a frag_list containing 2 additional sk_buff) High speed TCP flows benefit from this extension by lowering TCP stack cpu usage (less packets stored in receive queue, less ACK packets processed) Forwarding setups could be hurt, as such skbs will need to be linearized, although its not a new problem, as GRO could already provide skbs with a frag_list. We could make the 65536 bytes threshold a tunable to mitigate this. (First time we need to linearize skb in skb_needs_linearize(), we could lower the tunable to ~16*1460 so that following skb_gro_receive() calls build smaller skbs) Signed-off-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S.
