num_grat_arp
Specifies the number of gratuitous ARPs to be issued after a
failover event. One gratuitous ARP is issued immediately after
the failover, subsequent ARPs are sent at a rate of one per link
monitor interval (arp_interval or miimon, whichever is active).
The valid range is 0 - 255; the default value is 1. This option
affects only the active-backup mode. This option was added for
bonding version 3.3.0.
num_unsol_na
Specifies the number of unsolicited IPv6 Neighbor Advertisements
to be issued after a failover event. One unsolicited NA is issued
immediately after the failover.
Specify the number of peer notifications (gratuitous ARPs and
unsolicited IPv6 Neighbor Advertisements) to be issued after a
failover event. As soon as the link is up on the new slave
(possibly immediately) a peer notification is sent on the
bonding device and each VLAN sub-device. This is repeated at
each link monitor interval (arp_interval or miimon, whichever
is active) if the number is greater than 1.
The valid range is 0 - 255; the default value is 1. This option
affects only the active-backup mode. This option was added for

The valid range is 0 - 255; the default value is 1. These options
affect only the active-backup mode. These options were added for
bonding versions 3.3.0 and 3.4.0 respectively.
From Linux 2.6.40 and bonding version 3.7.1, these notifications
are generated by the ipv4 and ipv6 code and the numbers of
repetitions cannot be set independently.

REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not

MAC and VLAN anti-spoofing feature
----------------------------------
When a malicious driver attempts to send a spoofed packet, it is dropped by
the hardware and not transmitted. An interrupt is sent to the PF driver
notifying it of the spoof attempt.
When a spoofed packet is detected the PF driver will send the following
message to the system log (displayed by the "dmesg" command):
Spoof event(s) detected on VF(n)
Where n=the VF that attempted to do the spoofing.

Broadcom introduced new bus as replacement for older SSB. It is based on AMBA,
however from programming point of view there is nothing AMBA specific we use.
Standard AMBA drivers are platform specific, have hardcoded addresses and use
AMBA standard fields like CID and PID.
In case of Broadcom's cards every device consists of:
1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
as standard AMBA device. Reading it's CID or PID can cause machine lockup.
2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
and PIDs (0x103BB369), but we do not use that info for anything. One of that
devices is used for managing Broadcom specific core.
Addresses of AMBA devices are not hardcoded in driver and have to be read from
EPROM.
In this situation we decided to introduce separated bus. It can contain up to
16 devices identified by Broadcom specific fields: manufacturer, id, revision
and class.
