9645b4dc68 Make sure to read the last byte of EEPROM descriptor. Previously
the last byte of the ethernet address was not read which in turn
resulted in getting 5 out of the 6 bytes of ethernet address and
always returned ENOENT. I did not notice the bug on FPGA version
because of additional configuration data in EEPROM.

2c490bb4c3 Read PCI device id instead of PCI revision id. Also checks the read
device id is JMC260 family. Previously it just verified the deivce
is JMC260 Rev A0. This will make it easy for newer JMC2xx support.

514fd19ec3 Add workaround for occasional packet loss issue of JMC250 A2
when it runs on half-duplex media.
While I'm here add register definition for GPREG1. ATM the GPREG1
register is only valid for JMC250 A1/A2.

f94dfca526 Add workaround for CRC errors seen at 100Mbps on JMC250 A2.
While here update chip revision number of JMC250/JMC260 from the
latest datasheet.

25c768ed0d Correct 1000Mbps link handling logic for JMC250. This should make
jme(4) run on 1000Mbps link.

1a8fa7ea7b Add driver support for PCIe adapters based on JMicron JMC250
gigabit ethernet and JMC260 fast ethernet controllers. ATM jme(4)
supports all hardware features except RSS and multiple Tx/Rx queue.

In these days most ethernet controller vendors take a ply of
concealing hardware detailes from open source developers. As
contrasted with these vendors JMicron provided all necessary
information needed to write a stable driver during driver writing
and answered many questions I had. They even helped fixing driver
bugs with protocol analyzer. Many thanks to JMicron for their
support of FreeBSD.
