net/mlx5: Change POOL_NEXT_SIZE define value and make it global

2025-05-29T09:13:10Z

[ Upstream commit 80df31f384b4146a62a01b3d4beb376cc7b9a89e ] Change POOL_NEXT_SIZE define value from 0 to BIT(30), since this define is used to request the available maximum sized flow table, and zero doesn't make sense for it, whereas some places in the driver use zero explicitly expecting the smallest table size possible but instead due to this define they end up allocating the biggest table size unawarely. In addition move the definition to "include/linux/mlx5/fs.h" to expose the define to IB driver as well, while appropriately renaming it.

net/mlx5e: Add correct match to check IPSec syndromes for switchdev mode

2025-05-29T09:13:08Z

[ Upstream commit 85e4a808af2545fefaf18c8fe50071b06fcbdabc ] In commit dddb49b63d86 ("net/mlx5e: Add IPsec and ASO syndromes check in HW"), IPSec and ASO syndromes checks after decryption for the specified ASO object were added. But they are correct only for eswith in legacy mode. For switchdev mode, metadata register c1 is used to save the mapped id (not ASO object id). So, need to change the match accordingly for the check rules in status table.

net/mlx5: fs, add HWS packet reformat API function

2025-01-14T03:21:08Z

Add packet reformat alloc and dealloc API functions to provide packet reformat actions for steering rules. Add HWS action pools for each of the following packet reformat types: - decapl3: decapsulate l3 tunnel to l2 - encapl2: encapsulate l2 to tunnel l2 - encapl3: encapsulate l2 to tunnel l3 - insert_hdr: insert header In addition cache remove header action for remove vlan header as this is currently the only use case of remove header action in the driver.

net/mlx5: use do_aux_work for PHC overflow checks

2025-01-09T11:37:11Z

The overflow_work is using system wq to do overflow checks and updates for PHC device timecounter, which might be overhelmed by other tasks. But there is dedicated kthread in PTP subsystem designed for such things. This patch changes the work queue to proper align with PTP subsystem and to avoid overloading system work queue. The adjfine() function acts the same way as overflow check worker, we can postpone ptp aux worker till the next overflow period after adjfine() was called.
