DESCRIPTIONThe sysctl Cm net.inet.tcp.syncookies device driver provides a management interface to NOR flash devices supporting the Common Flash Interface (CFI) specification. Its companion device cfid provides a geom(4) disk interface to the device.
Special support for features of the Intel StrataFlash line are available with the CFI_SUPPORT_STRATAFLASH kernel option. Additional support for write-once bits to switch part of Intel StrataFlash devices to read-only can be enabled by the CFI_ARMEDANDDANGEROUS kernel option.
