Subject: [PATCH iwl-next v5 0/9] igc: Add support for Frame Preemption feature in IGC
Introduces support for the FPE feature in the IGC driver.
The patches aligns with the upstream FPE API:
https://patchwork.kernel.org/project/netdevbpf/cover/20230220122343.1156614-1-vladimir.oltean@nxp.com/
https://patchwork.kernel.org/project/netdevbpf/cover/20230119122705.73054-1-vladimir.oltean@nxp.com/
It builds upon earlier work:
https://patchwork.kernel.org/project/netdevbpf/cover/20220520011538.1098888-1-vinicius.gomes@intel.com/
The patch series adds the following functionalities to the IGC driver:
a) Configure FPE using `ethtool --set-mm`.
b) Display FPE settings via `ethtool --show-mm`.
c) View FPE statistics using `ethtool --include-statistics --show-mm'.
e) Block setting preemptible tc in taprio since it is not supported yet.
Existing code already blocks it in mqprio.
Change Log:

- olininfo_status to use host byte order (Simon)
- status_error should host byte type (Simon)
- Some code was misplaced in the wrong patch (Vladimir)
- Mix of tabs and spaces in patch description (Vladimir)
- Created igc_is_pmac_enabled() to reduce code repetition (Vladimir)
v3 -> v4:
- Fix compilation warnings introduced by this patch series
v2 -> v3:

- Remove unnecessary error check in igc_fpe_init_tx_descriptor() (Vladimir)
- Additional places to use FIELD_PREP() instead of manual bit manipulation (Vladimir)
- IGC_TXD_POPTS_SMD_V and IGC_TXD_POPTS_SMD_R type change to enum (Vladimir)
- Remove unnecessary netif_running() check in igc_fpe_xmit_frame (Vladimir)
- Rate limit print in igc_fpe_send_mpacket (Vladimir)
v1 -> v2:

- igc to use common library for verification (Vladimir)
- Fix syntax for kernel-doc to use "Return:" (Vladimir)
- Use FIELD_GET instead of manual bit masking (Vladimir)
- Don't assign 0 to statistics counter in igc_ethtool_get_mm_stats() (Vladimir)
- Use pmac-enabled as a condition to allow MAC address value 0 (Vladimir)
- Define macro register value in increasing value order (Vladimir)
- Fix tx-min-frag-size handling for igc (Vladimir)
- Handle link state changes with verification in igc (Vladimir)
