the MAC address from EEPROM correctly, and so on, and also

description "
The ethernet device can maintain statistics about the network,
specifically a great variety of error rates which are useful
for network management. SNMP for example uses this
information. There is some performance cost in maintaining
this information; disable this option to recoup that."

description "
The i82544 keeps internal counters, and it is possible to
acquire these. But the i82544 (reputedly) does not service
the network whilst uploading the data to RAM from its
internal registers. If throughput is a problem, disable
this option to acquire only those statistics gathered by
software, so that the i82544 never sleeps."

description "
The ioctl() socket call with operand SIOCSIFHWADDR sets the
interface hardware address - the MAC address or ethernet
address. This option causes the new MAC address to be written
into the EEPROM associated with the interface, so that the new
MAC address is permanently recorded. Doing this should be a
carefully chosen decision, hence this option."

description "
An RX descriptor is used for each ethernet frame required
to be passed to the upper networking layers. This option
sets the maximum number of these. Higher numbers use more
memory, lower numbers will reduce performance. The system
appears to work OK with as few as 8 descriptors but limps
painfully with only 4. Performance is better with more than
8, but assuming the size of non-cached (so useless for anything
else) memory window is 1Mb, we might as well use it all.
128 RX and TX descriptors uses the whole 1Mb, near enough."
