When enabling a range of VLANs on a bridged port we can configure
flooding for these VLANs by one register access instead of calling the
same register for each VLAN. This is accomplished by using the 'range'
field of the Switch Flooding Table Register (SFTR).

I'm planning to create similar directories for all vendors, currently we

There's also a new driver rtl8xxxu for few realtek USB devices. This

The Qlogic Everest Driver is the backend module for the QL4xxx ethernet

This module serves two main purposes:
1. It's responsible to contain all the common code that will be shared
between the various drivers that would be used with said line of
products. Flows such as chip initialization and de-initialization
fall under this category.
2. It would abstract the protocol-specific HW & FW components, allowing
the protocol drivers to have a clean APIs which is detached in its
slowpath configuration from the actual HSI.
This adds a very basic module without any protocol-specific bits.
I.e., this adds a basic implementation that almost entirely falls under

While the current driver mostly supports BCM7445 which has a hardcoded
location for its MoCA port on port 7 and port 0 for its internal PHY,
this is not necessarily true for all other chips out there such as
BCM3390 for instance.
Walk the list of ports from Device Tree, get their port number ("reg"
property), and then parse the "phy-mode" property and initialize two
internal variables: moca_port and a bitmask of internal PHYs. Since we
use interrupts for the MoCA port, we introduce two helper functions to
enable/disable interrupts and do this at the appropriate bank (INTRL2_0
or INTRL2_1).

Intel Wired LAN Driver Updates 2015-10-23
This series contains updates to i40e, i40evf, if_link, ixgbe and ixgbevf.
Anjali adds a workaround to drop any flow control frames from being
transmitted from any VSI, so that a malicious VF cannot send flow control
or PFC packets out on the wire. Also fixed a bug in debugfs by grabbing
the filter list lock before adding or deleting a filter.
Akeem fixes an issue where we were unconditionally returning VEB bridge
mode before allowing LB in the add VSI routine, resolve by checking if
the bridge is actually in VEB mode first.
Mitch fixed an issue where the incorrect structure was being used for
VLAN filter list, which meant the VLAN filter list did not get
processed correctly and VLAN filters would not be re-enabled after any
kind of reset.
Helin fixed a problem of possibly getting inconsistent flow control
status after a PF reset. The issue was requested_mode was being set
with a default value during probe, but the hardware state could be a
different value from this mode.
Carolyn fixed a problem where the driver output of the OEM version
string varied from the other tools.
Jean Sacren fixes up kernel documentation by fixing function header
comments to match actual variables used in the functions. Also
cleaned up variable initialization, when the variable would be
over-written immediately.
Hiroshi Shimanoto provides three patches to add "trusted" VF by adding
netlink directives and an NDO entry. Then implement these new controls
in ixgbe and ixgbevf. This series has gone through several iterations
to address all the suggested community changes and concerns.

The limitation of the number of multicast address for VF is not enough
for the large scale server with SR-IOV feature. IPv6 requires the multicast
MAC address for each IP address to handle the Neighbor Solicitation
message. We couldn't assign over 30 IPv6 addresses to a single VF.
This patch introduces the new mailbox API, IXGBE_VF_UPDATE_XCAST_MODE,
to update multicast mode of VF. This adds 3 modes;
- NONE only L2 exact match addresses or Flow Director enabled
- MULTI BAM and ROMPE set
- ALLMULTI BAM, ROMPE and MPE set
If a guest VF user wants over 30 MAC multicast addresses, set IFF_ALLMULTI
to request PF to update xcast mode to enable VF multicast promiscuous mode.
On the other hand, enabling VF multicast promiscuous mode may affect
security and performance in the network of the NIC. Only trusted VF can
enable multicast promiscuous mode. The behavior of untrusted VF is the
same as previous version.
