TCP-NV (New Vegas) is a major update to TCP-Vegas. An earlier version of
NV was presented at 2010's LPC (slides). It is a delayed based
congestion avoidance for the data center. This version has been tested
within a 10G rack where the HW RTTs are 20-50us.

The first patch replaces two arguments in the pkts_acked() function

With a little work we can clean up some unnecessary logic jumping and

Store off the VF API version for use when figuring out the VF driver
capabilities. Add support for the VF driver handing its capabilities to
the PF driver and then use this information when sending VF resource
information back to the VF driver.

From: Mitch Williams
The most common type of reset that the VF will encounter is a PF reset
that cascades down into a VF reset for each VF. In this case, the VF
will always be assigned the same VSI and recovery is fairly simple.
However, in the case of 'bigger' resets, such as a Core or EMP rese

This driver fully supports VF drivers using both the 1.0 and 1.1
versions of the virtual channel API. However, VF drivers using
version 1.0 get upset if we provide them with a version other than
that, and refuse to play with us.
Correct this by checking the VFs API version a

To prepare for the changes coming up in the X722 device and future
devices, the virtual channel interface has to change slightly. The VF
driver can now report what its capable of supporting, which then informs
the PF driver when it sends the configuration information back to

Use the ARRAY_SIZE macro rather than calculating sizeof(a)/sizeof(a[0]).
Also directly replace the code rather than using an unnecessary define.

This patch extends the reporting of the RSS key and hash table by
adding support for X550 VFs. The difference is that X550 VFs have
their own registers for RSS key and indirection table, so there is
no need to query the PF.
The RSS key and indirection table are stored in the

The driver lacks pm_qos_remove_request in error handling (err_req_irq) of
e1000_open, and qos request inserted by pm_qos_add_request is not removed.
This patch add pm_qos_remove_request in error handling to fix it.

I cant think of a way to fix the current problem with my patch...
I guess it's not obvious that adding CONFIG_MPLS_IPV6 would solve
the problem perfectly.

This patch fixes error in the setting of the hw statistics
module base for K2HK platform. In K2HK although there are
4 hw statistics modules, but only 2 are visible at a time.
Thus when setting up the pointers to the base of the
corresponding hw statistics modules, modules 0 and 2 should
point to
This patch fixes a bug in which the timer routine synchronized
against the ethtool-triggered statistics updates with spin_lock_bh().
A timer function is itself a bottom-half, so this should be
spin_lock().

The CPSW driver keeps internally some, but not all, of
the statistics available in the hw statistics modules. Furthermore,
some of the locations in the hw statistics modules are reserved and
contain no useful information. Prior to this patch, the driver

In certain applications it's beneficial to allow the CPSW h/w
stats counters to continue to increment even while the kernel
