The jumbo frame configuration in the MAC/PHY should be reverted on 82579 and newer parts when the interface is brought down (not just when the MTU is changed back to standard frame size) otherwise iAMT connections (e.g. SoL, IDE-R) will be dropped and cannot be re-acquired until the MTU is changed again.

In attempting to resolve a minor merge conflict, commit e5f2ef7a (Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net) accidentally dropped a call to pci_clear_master() that was intended to remain in place. Commit 4e0855df (e1000e: fix pci-device enable-counter balance) replaced a call to pci_disable_device() by one to pci_clear_master(). And then commit 66148bab (e1000e: fix runtime power management transitions) deleted a number of lines starting two lines following that call.

This patch centralizes computing of max rx/tx qlen, because: - RX_QLEN()/TX_QLEN() is called in hot path - computing depends on device's usb speed, now we have ls/fs, hs, ss, so more checks need to be involved - in fact, max rx/tx qlen should not only depend on device USB speed, but also depend on ethernet link speed, so we need to consider that in future. - if SG support is done, max tx qlen may need change too Generally, hard_mtu and rx_urb_size are changed in bind(), reset() and link_reset() callback, and change mtu network operation, this patches introduces the API of usbnet_update_max_qlen(), and calls it in above path.

Inspired by commit f09e2249 (macvtap: restore vlan header on user read). This patch adds hardware vlan tx support for tuntap. This is done by copying vlan header directly into userspace in tun_put_user() instead of doing it through __vlan_put_tag() in dev_hard_start_xmit(). This eliminates one unnecessary memmove() in vlan_insert_tag() for 802.1ad and 802.1q traffic. pktgen test shows about 20% improvement for 802.1q traffic: Before: 662149pps 317Mb/sec (317831520bps) errors: 0 After: 801033pps 384Mb/sec (384495840bps) errors: 0 Cc: Basil Gor <basil.gor@gmail.com> Cc: Michael S.

The MinnowBoard uses an AR803x PHY with the PCH GBE which requires special handling. Use the MinnowBoard PCI Subsystem ID to detect this and add a pci_device_id.driver_data structure and functions to handle platform setup. The AR803x does not implement the RGMII 2ns TX clock delay in the trace routing nor via strapping. Add a detection method for the board and the PHY and enable the TX clock delay via the registers. This PHY will hibernate without link for 10 seconds. Ensure the PHY is awake for probe and then disable hibernation. A future improvement would be to convert pch_gbe to using PHYLIB and making sure we can wake the PHY at the necessary times rather than permanently disabling it.

Idea of this patch is to add optional limitation of number of unsent bytes in TCP sockets, to reduce usage of kernel memory. TCP receiver might announce a big window, and TCP sender autotuning might allow a large amount of bytes in write queue, but this has little performance impact if a large part of this buffering is wasted : Write queue needs to be large only to deal with large BDP, not necessarily to cope with scheduling delays (incoming ACKS make room for the application to queue more bytes) For most workloads, using a value of 128 KB or less is OK to give applications enough time to react to POLLOUT events in time (or being awaken in a blocking sendmsg()) This patch adds two ways to set the limit : 1) Per socket option TCP_NOTSENT_LOWAT 2) A sysctl (/proc/sys/net/ipv4/tcp_notsent_lowat) for sockets not using TCP_NOTSENT_LOWAT socket option (or setting a zero value) Default value being UINT_MAX (0xFFFFFFFF), meaning this has no effect. This changes poll()/select()/epoll() to report POLLOUT only if number of unsent bytes is below tp->nosent_lowat Note this might increase number of sendmsg()/sendfile() calls when using non blocking sockets, and increase number of context switches for blocking sockets. Note this is not related to SO_SNDLOWAT (as SO_SNDLOWAT is defined as : Specify the minimum number of bytes in the buffer until the socket layer will pass the data to the protocol) Tested: netperf sessions, and watching /proc/net/protocols "memory" column for TCP With 200 concurrent netperf -t TCP_STREAM sessions, amount of kernel memory used by TCP buffers shrinks by ~55 % (20567 pages instead of 45458) lpq83:~# echo -1 >/proc/sys/net/ipv4/tcp_notsent_lowat lpq83:~# (super_netperf 200 -t TCP_STREAM -H remote -l 90 &); sleep 60 ; grep TCP /proc/net/protocols TCPv6 1880 2 45458 no 208 yes ipv6 y y y y y y y y y y y y y n y y y y y TCP 1696 508 45458 no 208 yes kernel y y y y y y y y y y y y y n y y y y y lpq83:~# echo 131072 >/proc/sys/net/ipv4/tcp_notsent_lowat lpq83:~# (super_netperf 200 -t TCP_STREAM -H remote -l 90 &); sleep 60 ; grep TCP /proc/net/protocols TCPv6 1880 2 20567 no 208 yes ipv6 y y y y y y y y y y y y y n y y y y y TCP 1696 508 20567 no 208 yes kernel y y y y y y y y y y y y y n y y y y y Using 128KB has no bad effect on the throughput or cpu usage of a single flow, although there is an increase of context switches.
