Modified files:
sys/pci if_tx.c if_txvar.h
Log:
Implemented workaround for EPIC's Application Note 7-15 (concerning
chip int. and ext. clock synchronisation). Fixed workaround for
transmit threshold underrun. Added volatile keyword to CSR_READ_* and
CSR_WRITE_* macroses. Added DELAYs to eliminate randomness caused
by processor speed. Fixed all TXCON and RXCON registers to be accessed
only when chip is idle, as manual told. Changed epic_init_phy to
drop link by isolating and going loopback, should should force link
partner to restart autonegotiation.
