* RDMA/nes: Delete impossible debug printsLeon Romanovsky2018-09-051-9/+0
| | | | | | | | | | | The pci-core and net-core logic ensure that parameters provided to nes_probe() and nes_netdev_open() are valid, hence the assert print are not possible.

These structures are used by user-space library driver (libmlx4) and currently manually copied to that library.

| | | | | | | | | | | | Support for Packed and Unaligned (PAU) FPDUs is needed for interoperability between NES and non-NES nodes. When the NES hardware detects a PAU frame, it will pass it to the driver to process the frame. NES driver creates a new frame for each FPDU and forwards it to the hardware to be sent to its associated qp.

| | | | | | | | | | | | In case of SFP+ PHY, link status check at interrupt processing can give false results. For proper link status change detection a delayed recheck is needed to give nes registers time to settle. Add a periodic link status recheck scheduled at interrupt to detect potential delayed registers state changes.

Wrap this up in functions nes_free_cqp_request() and nes_put_cqp_request() to simplify such code.

* RDMA/nes: Fix up nes_lro_max_aggr module parameterRoland Dreier2008-05-131-1/+0
| | | | | | | | | | | | | | | | | | | | Fix some bugs with the max_aggr module parameter added with LRO support: - The module parameter value ignored and not actually used to set lro_mgr.max_aggr. - MODULE_PARM_DESC had a typo "_mro_" instead of "_lro_" so it didn't end up describing the actual module parameter. - The nes_lro_max_aggr variable was declared as unsigned, but the module_param line said "int" instead of "uint" for the type. - The default value for the parameter was stuck in the permissions field of module_param, which led to nonsensical permissions for the file under /sys/module/iw_nes/param. - The parameter was used in only one file but defined in another, which led to the variable being global for no good reason.
