This structure is filled by mlx5_pci_probe(), outside of this function
it should be treated as *read only*.

This configuration struct will be used for the Tx/Rx queue setup to

device capabilities.
In addition it will be used by the burst selection function to decide

net/mlx5: fix overwriting bit-fields in SW Rx queue

Bit-fields in mlx5_rxq_data can be changed on the fly by a control plane -
e.g. rxq->mark. However, vectorized Rx uses a bit-field to mark pending
errors. Even if one bit is written, consequence is to write the whole
integer and this can cause a synchronization issue - two entities write to
a same block without locking. As the pending_err bit is entirely internal
use for the datapath, this can be replaced with a local variable.
