LAN91C111 driver bug

in the file "altera_avalon_lan91c111.c" in the path "...\components\altera_avalon_lan91c111\UCOSII\src" the assignment:

IOWR_ALTERA_AVALON_LAN91C111_TCR( dev-> base_addr,ALTERA_AVALON_LAN91C111_TCR_TXENA_MSK |

ALTERA_AVALON_LAN91C111_TCR_PAD_EN_MSK);

in the fuction "low_level_init", overwrite the previous register assignment targeted for full-duplex connection:

IOWR_ALTERA_AVALON_LAN91C111_TCR(dev->base_addr,value);

in the fuction "configure_phy", causing collision and lost packet in full-duplex trasmissions.

You can replace the first assignment with:

value = IORD_ALTERA_AVALON_LAN91C111_TCR(dev->base_addr);

value |= ALTERA_AVALON_LAN91C111_TCR_TXENA_MSK | ALTERA_AVALON_LAN91C111_TCR_PAD_EN_MSK ;

IOWR_ALTERA_AVALON_LAN91C111_TCR(dev->base_addr,value);

declaring:

alt_u16 value;
