In LACP mode with broadcast_neighbor enabled, after LACP protocol recovery, the port can transmit packets. However, if the bond port doesn't send gratuitous ARP/ND packets to the switch, the switch won't return packets through the current interface. This causes traffic imbalance. To resolve this issue, when LACP protocol recovers, send ARP/ND packets if broadcast_neighbor is enabled. Cc: Jay Vosburgh <jv@jvosburgh.net> Cc: "David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
