Subject: [PATCH] ice: introduce new E825C devices family
Introduce new Intel Ethernet E825C family devices.
Add new PCI device IDs which are going to be supported by the
driver:
- 579C: Intel(R) Ethernet Connection E825-C for backplane
- 579D: Intel(R) Ethernet Connection E825-C for QSFP
- 579E: Intel(R) Ethernet Connection E825-C for SFP
- 579F: Intel(R) Ethernet Connection E825-C for SGMII
Add helper function ice_is_e825c() to verify if the running device
belongs to E825C family.
