I would start with network card manual.
If you can't find one, or there wasn't one delivered with it, using google for each is good way to find answers. For list that is shown in screenshot:
- Auto Disable Gigabit: running gigabit speed without any need uses more power, so there is option to disable it automatically when not in use
- Flow Control: Flow Control is mechanism for handling send/receive speeds without outrunning slower party
- Green Ethernet: Proprietary power saving technology
- Interrupt Moderation: no interrupt for every packet, but after timeout/enough data
- IPv4 Checksum Offload: Network controller will calculate checksums, instead of CPU.
- Jumbo Frame: support for larger frames than ethernet default (1500 bytes)
- Large Send Offload: method for sending large amount of data to network controller, which will then process it at once
- Network Address: most probably MAC address of network card.
- Priority & VLAN: priority: QOS feature. VLAN: Virtual LAN
- Receive Buffers: Size of buffers for received data
- Receive Side Scaling: support for using multiple processor while receiving
- Shutdown Wake-On-Lan: Enable wake-on-lan support (possibility to remotely start up computer with special network packet)
- Speed & Duplex: default speed (for example 10Mb/s, 100Mb/s) and duplex (half- or full-)
