Subject: [PATCH v3 net-next 00/13] Add more feautues for ENETC v4 - round 2

This patch set adds the following features.
1. Compared with ENETC v1, the formats of tables and command BD of ENETC
v4 have changed significantly, and the two are not compatible. Therefore,
in order to support the NETC Table Management Protocol (NTMP) v2.0, we
introduced the netc-lib driver and added support for MAC address filter
table and RSS table.
2. Add MAC filter and VLAN filter support for i.MX95 ENETC PF.
3. Add RSS support for i.MX95 ENETC PF.
4. Add loopback support for i.MX95 ENETC PF.

v1 Link: https://lore.kernel.org/imx/20250103060610.2233908-1-wei.fang@nxp.com/
v2 changes
1. Change NTMP_FILL_CRD() and NTMP_FILL_CRD_EID to functions
2. Fix the compile warning in enetc4_pf.c
v2 Link: https://lore.kernel.org/imx/20250113082245.2332775-1-wei.fang@nxp.com/
v3 changes
1. Rename ntmp_formats.h to ntmp_private.h, becuase in addition to
   defining some table formats, some macros and function declarations
   will be added to this header file in the future
2. Add struct ntmp_dma_buf, so refactor ntmp_alloc_data_mem() and
   ntmp_free_data_mem() accordingly
3. Add the setting for cache attributes of command BD Ring in
   enetc4_setup_cbdr()
4. Remove __free() and scoped_guard() from patch "net: enetc: add MAC
   filter for i.MX95 ENETC PF", as these cleanup APIs are discouraged
   within networking drivers.
5. Remove patch "net: enetc: make enetc_set_rxfh() and enetc_get_rxfh()
   reusable" in v2, and add enetc_set_rss_key() and enetc_get_rss_key()
   instead of adding .set_rss_key() and .get_rss_key() to enetc_pf_ops
6. Separate patch " net: enetc: check if the RSS hfunc is toeplitz" from
   patch "net: enetc: add RSS support for i.MX95 ENETC PF"
