net/mlx5e: Tidy up IPsec NAT-T SA discovery

2023-12-05T06:11:52Z

IPsec NAT-T packets are UDP encapsulated packets over ESP normal ones. In case they arrive to RX, the SPI and ESP are located in inner header, while the check was performed on outer header instead. That wrong check caused to the situation where received rekeying request was missed and caused to rekey timeout, which "compensated" this failure by completing rekeying.

net/mlx5e: Honor user choice of IPsec replay window size

2023-12-05T06:11:51Z

Users can configure IPsec replay window size, but mlx5 driver didn't honor their choice and set always 32bits. Fix assignment logic to configure right size from the beginning.

vdpa/mlx5: Enable hw support for vq descriptor mapping

2023-11-01T13:19:57Z

Vq descriptor mappings are supported in hardware by filling in an additional mkey which contains the descriptor mappings to the hw vq. A previous patch in this series added support for hw mkey (mr) creation for ASID 1. This patch fills in both the vq data and vq descriptor mkeys based on group ASID mapping. The feature is signaled to the vdpa core through the presence of the .get_vq_desc_group op.

net/mlx5: Parallelize vhca event handling

2023-10-14T17:16:29Z

At present, mlx5 driver have a general purpose event handler which not only handles vhca event but also many other events. This incurs a huge bottleneck because the event handler is implemented by single threaded workqueue and all events are forced to be handled in serial manner even though application tries to create multiple SFs simultaneously. Introduce a dedicated vhca event handler which manages SFs parallel creation.
