Intel FM10000 (FM10K) is an Ethernet switch chipset family. There are network interface cards based on FM10K, such as Silicom PE3100G2DQIR Server Adapter.

I have been developing the host driver and software that operates the FM10K internal switch. Here, I write up some technical notes on it. Note that this is my personal note, and please refer to the official technical documents provided by Intel for correct and detailed information.

• PEP: PCIe End Point
• EPL: Ethernet Port Logic
• PF: Physical Function
• VF: Virtual Function
• SM: Switch manager
• BSM: Boot State Machine
