2020-04-29cxgb4: fix large delays in PTP synchronizationRahul Lakkireddy1-0/+3
[ Upstream commit bd019427bf3623ee3c7d2845cf921bbf4c14846c ] Fetching PTP sync information from mailbox is slow and can take up to 10 milliseconds. Reduce this unnecessary delay by directly reading the information from the corresponding registers.

2018-05-16cxgb4: update LE-TCAM collection for T6Rahul Lakkireddy1-0/+1
For T6, clip table is separated from main TCAM. So, update LE-TCAM collection logic to collect clip table TCAM as well. IPv6 takes 4 entries in clip table TCAM compared to 2 entries in main TCAM. Also, in case of errors, keep LE-TCAM collected so far and set the status to partial dump.

2017-01-16cxgb4: Shutdown adapter if firmware times out or errors outHariprasad Shenai1-0/+8
Perform an emergency shutdown of the adapter and stop it from continuing any further communication on the ports or DMA to the host. This is typically used when the adapter and/or firmware have crashed and we want to prevent any further accidental communication with the rest of the world. This will also force the port Link Status to go down -- if register writes work -- which should help our peers figure out that we're down.
