DESCRIPTIONThe sysctl Cm net.inet.tcp.syncookies driver provides support for the Sun Cassini/Cassini+ and National Semiconductor DP83065 Saturn Gigabit Ethernet controllers found on-board in Sun UltraSPARC machines and as add-on cards.
All controllers supported by the sysctl Cm net.inet.tcp.syncookies driver have TCP/UDP checksum offload capability for both receive and transmit, support for the reception and transmission of extended frames for vlan(4) and an interrupt coalescing/moderation mechanism as well as a 512-bit multicast hash filter.
The sysctl Cm net.inet.tcp.syncookies driver also supports Jumbo Frames (up to 9022 bytes), which can be configured via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility configures the adapter to receive and transmit Jumbo Frames.
HARDWAREThe chips supported by the sysctl Cm net.inet.tcp.syncookies driver are:
- National Semiconductor DP83065 Saturn Gigabit Ethernet
- Sun Cassini Gigabit Ethernet
- Sun Cassini+ Gigabit Ethernet
The following add-on cards are known to work with the sysctl Cm net.inet.tcp.syncookies driver at this time:
- Sun GigaSwift Ethernet 1.0 MMF (Cassini Kuheen) (part no. 501-5524)
- Sun GigaSwift Ethernet 1.0 UTP (Cassini) (part no. 501-5902)
- Sun GigaSwift Ethernet UTP (GCS) (part no. 501-6719)
- Sun Quad GigaSwift Ethernet UTP (QGE) (part no. 501-6522)
- Sun Quad GigaSwift Ethernet PCI-X (QGE-X) (part no. 501-6738)
NOTESOn sparc64 the sysctl Cm net.inet.tcp.syncookies driver respects the local-mac-address? system configuration variable which can be set in the Open Firmware boot monitor using the setenv command or by eeprom(8). If set to ``false '' (the default), the sysctl Cm net.inet.tcp.syncookies driver will use the system's default MAC address for all of its devices. If set to ``true '' the unique MAC address of each interface is used if present rather than the system's default MAC address.
Supported interfaces having their own MAC address include on-board versions on boards equipped with more than one Ethernet interface and all add-on cards.
