rq->hw_mtu is used in function en_rx.c/mlx5e_skb_from_cqe_mpwrq_linear()
to catch oversized packets. If FCS is concatenated to the end of the
packet then the check should be updated accordingly.
Rx rings initialization (mlx5e_init_rxq_rq()) invoked for every new set
of channels, as part of mlx5e_safe_switch_params(), unknowingly if it
runs with default configuration or not. Current rq->hw_mtu
initialization assumes default configuration and ignores
params->scatter_fcs_en flag state.
Fix this, by accounting for params->scatter_fcs_en flag state during
rq->hw_mtu initialization.
In addition, updating rq->hw_mtu value during ingress traffic might
lead to packets drop and oversize_pkts_sw_drop counter increase with no
good reason. Hence we remove this optimization and switch the set of
channels with a new one, to make sure we don't get false positives on
the oversize_pkts_sw_drop counter.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
