The driver originally gets the full-duplex configuration
from the PHCON1 register and PDPXMD bit as stated by the
ENC298J60 specification document section 2.6 "LED Configuration".
This section trust the board to LEDB connection to signal the
full-duplex configuration.
This commit gets the full-duplex configuration from Kconfig
symbols to allow a proper functionality even when the board
is not connecting LEDB apropriately.

ENCC28J60 specs section 6.5 "MAC Initialization settings"
state that MACON3(7:5) register configure automatic padding and CRC.
It also states that the configuration 111 and 011 both configure as
all short frames to be zero padded with a valid CRC appended.
Nevertheless, experimentally, there are ocassions when configuring as 111
frames does not have a CRC appended. This frames could be rejected
by the receiver if it is configured to do so.
This commit changes configuration from 111 to 011, which is not
presenting that behavior.

Per spec document, RXEN bit corresponds to bit 2
of the ECON1 register instead of bit 1.

The rx fiber call contiki IP stack functions to register
received frames. This interaction requires more stack memory
in the rx fiber stack to avoid memory corruption.

SPI bus is a shared resource between tx and rx processes.
The access to it must be synchronized to allow a rx process to
happen even when a tx process is taking place.
ECON1 register must be saved by the rx process and recovered
at the end to ensure that the tx process will continue operating
in the same register bank.
