- Remove redundant return value check in buffer manager - Make sure the port is admin down before vs test - Move the code recovering the port's admin status to the finally block in order to guarantee the port will be admin down in any case. Signed-off-by: Stephen Sun <stephens@nvidia.com>
…FFER_QUEUE table Originally, there was one fvVector in doSpeedUpdateTask for both tables. It was OK since there was no intersection between its lifespan of both tables. However, when reclaiming buffer feature is introduced, its lifespan of both tables interleave, which requires it to be cleared when it was for one table and will be for another. This makes the code difficult to be understood and prevents the data fetched from redis db to be reused. To make the code clear and more efficient, a dedicated fvVector is introduced for each table.

…2011) - What I did It's to port #1837 to master to reclaim reserved buffer. As the way to do it differs among vendors, buffermgrd will: 1. Handle port admin down on Mellanox platform. - Not apply lossless buffer PG to an admin-down port - Remove lossless buffer PG (3-4) from a port when it is shut down. 2. Read lossless buffer PG (3-4) to a port when a port is started up. - Why I did it To support reclaiming reserved buffer when a port is shut down on Mellanox platform in traditional buffer model. - How I verified it sonic-mgmt test and vs test.

sonic-net#1837) What I did This PR adds support for an option to configure muxcable mode to a standby mode. The standby mode is in addition to auto\active\manual mode. The new output would look like this in case an standby arg is passed to the command line admin@sonic:~$ sudo config muxcable mode standby Ethernet0 admin@sonic:~$ sudo config muxcable mode standby all added an option to set muxcable mode to standby mode, in addition to existing auto/active/manual modes. How I did it added the changes in config/muxcable.py and added testcases How to verify it Ran the unit tests Signed-off-by: vaibhav-dahiya <vdahiya@microsoft.com>
