  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.
