Code Issues Releases Activity

Netlogic XLP network driver update

Browse Source 
Changes are to
- update board and network interface detection logic
- fix reading onboard CPLD in little-endian config
- print NAE frequency conrrectly for Bx chips
- update XAUI config to disable Rx/Tx until interface is up
