The 5717 sets up TSO slightly differently in the transmit path. It looks like this method will be the new way of doing things. This patch defines a flag to indicate this. Signed-off-by:

This patch consolidates the TSO capability discovery code into its own code block. The code that decides whether or not to allow TSO is then cleaned up. Finally, the patch consolidates all MSI and MSIX capability code into a single code block. Signed-off-by:

We need room for another TSO flag and it would be most efficient if it resided in tg3_flags2. This patch moves the TG3_FLG2_PROTECTED_NVRAM to tg3_flags3 to make room. Signed-off-by:

Recent changes in the TX error propagation require additional checking and masking of values returned from hard_start_xmit(), mainly to separate cases where skb was consumed. This aim can be simplified by changing the order of NETDEV_TX and NET_XMIT codes, because the latter are treated similarly to negative (ERRNO) values. After this change much simpler dev_xmit_complete() is also used in sch_direct_xmit(), so it is moved to netdevice.h. Additionally NET_RX definitions in netdevice.h are moved up from between TX codes to avoid confusion while reading the TX comment. Signed-off-by:

My last commit introduced an typo causing the compat_ioctl function to do nothing useful. The obvious way for an ioctl function to work is to look at the command, not the argument first. Signed-off-by:

The cu3088-driver used as common base for lcs- and ctcm-devices makes it difficult to assign the appropriate driver to an lcs-device or a ctcm-device. This patch eliminates the cu3088-driver and thus the root device "cu3088". Path /sys/devices/cu3088 is replaced with the pathes /sys/devices/lcs and /sys/devices/ctcm. Patch is based on a proposal from Cornelia Huck. Cc: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by:

While investigating for network latencies, I found inet_getid() was a contention point for some workloads, as inet_peer_idlock is shared by all inet_getid() users regardless of peers. One way to fix this is to make ip_id_count an atomic_t instead of __u16, and use atomic_add_return(). In order to keep sizeof(struct inet_peer) = 64 on 64bit arches tcp_ts_stamp is also converted to __u32 instead of "unsigned long". Signed-off-by:

When handling large number of netdevices, inet6_dump_addr() is very slow because it has O(N^2) complexity. Instead of scanning one single list, we can use the NETDEV_HASHENTRIES sub lists of the dev_index hash table, and RCU lookups. Signed-off-by:

The first "node" is supposed to be the cursor used in the for_each. The second "node" is ment literally and should not be macro expanded: it's the name of the hlist_node field from the inet_bind_bucket. This currently works because when inet_bind_bucket_for_each is called it's argument is still "node". Signed-off-by:

But we dump at most one skb (<= 8192 bytes ?), so rcu_read_lock holding time is small, unless we meet many netdevices without addresses. I wonder if its really common...

This patch pairs similar-numbered Rx and Tx queues onto a single MSI-X vector. For example, Tx queue 0 and Rx queue 0's interrupt with be ethX-RxTx-0. This allows for more efficient cleanup, since fewer interrupts will be firing during device operation. It also helps with a cleaner CPU affinity for IRQ affinity. Signed-off-by:

This patch does some refactoring work that I felt was needed after reviewing the changes recently submitted relating to the replacement of net_stats with netdev->stats. This patch essentially creates two different collections of stats. The first handles the adapter specific states and is stored in gstring_stats, and the second is for netdev specific stats and is stored in gstring_net_stats. Signed-off-by:

Both vlan and macvlan devices usually don't use a qdisc and immediately queue packets to the underlying device. Propagate transmission state of the underlying device to the upper layers so they can react on congestion and/or inform the sending process. Signed-off-by:

Currently the ->ndo_hard_start_xmit() callbacks are only permitted to return one of the NETDEV_TX codes. This prevents any kind of error propagation for virtual devices, like queue congestion of the underlying device in case of layered devices, or unreachability in case of tunnels. This patches changes the NET_XMIT codes to avoid clashes with the NETDEV_TX codes and changes the two callers of dev_hard_start_xmit() to expect either errno codes, NET_XMIT codes or NETDEV_TX codes as return value. In case of qdisc_restart(), all non NETDEV_TX codes are mapped to NETDEV_TX_OK since no error propagation is possible when using qdiscs. In case of dev_queue_xmit(), the error is propagated upwards.
