Linux native driver (MEN) for 16Z077_ETH and 16Z087_ETH
Download 13z07790.zip commit 2b15ba68456f0dcbf703a1fb875435dde64be4c7 (tag: 13Z077-90_02_00)

R: 1. major rework due to code for many EOL cards and simplified MAC address retrieval
2. Driver version can't be identified quick and simple to help MEN support
M: 1a. changed MAC retrieval order: 1. MAC registers 2. MAC EEPROM. 3. board ID EEPROM. 4. fallback: random MAC.
1b. removed support for old Z077 Core, P511, several PPC cards. Code size reduced by ca. 50%.
1c. use current DMA API, not pci_xxx DMA functions as recommended in kernel documentation.
1d. update version to 2.0
2. MODULE_VERSION() with git version stamp added to driver, can be dumped with modinfo tool (modinfo men_lx_z77)

men_16z077_eth.c
R: 1. Compilerwarning: incompatible pointer type of .ndo_vlan_rx_add_vid
2. several compilerwarnings about typecasts with gcc 4.8, kernel 3.14
M: 1. corrected declaration of z77_vlan_rx_add_vid
2. changed variable types to appropriate ones, use unsigned long etc.
Tested with iperf under Archlinux kernel 3.14.6
-----[ Revision 1.15 ]-----
[ 2014-06-17 16:11:02 by ts ]
men_16z077_eth.c
R: 1. from kernel 3.10 on build failed because of undefined symbols
2. under Arch linux 3.10.10 the board ID EEPROM wasnt found on F011C
M: 1. replace NETIF_xxx flags for VLAN support with xxx_CTAG_ as in 3.10.0 and up
2. increased I2C_MAX_ADAP_CNT to 32
-----[ Revision 1.14 ]-----
[ 2013-10-02 14:53:16 by ts ]
R: 1. on F75P transfers were hanging under heavy load
2. during tests on F75P multiple instances of netio etc. stopped working
M: 1. corrected typo in z77_irq (all IRQs except RXE were ack'ed, not RXF)
2. in send_packet() free skb buffers also before return due to TX busy
-----[ Revision 1.13 ]-----
[ 2013-07-10 18:39:17 by ts ]
R: minimum Framelen 0x40 made problem in customer application due
to PACKLEN register interpreting the value without FCS
M: changed header file, reverted this files last work checking for
other CPU back to 1.38 to avoid other side effects
-----[ Revision 1.12 ]-----
[ 2013-03-23 14:19:05 by ts ]

2. reworked IRQ masking/reenabling in z77_irq (Busy IRQ reenabling etc.)
-----[ Revision 1.10 ]-----
[ 2012-11-06 20:31:30 by ts ]
R: 1. support for Multicast reception requested by customer
2. MAC addresses for x86 boards were not generated according to ident EEprom
3. build failed for kernel versions > 3.0

[ 2011-03-16 19:18:08 by ts ]

[ 2010-11-25 17:51:39 by ts ]

3) new PHYs introduced in F218, F11S
4) MM1 MAC address wasnt fetched from EEPROM

-----[ Revision 1.5 ]-----
[ 2010-03-08 14:57:26 by ts ]
R: 1) driver used deprecated interrupt routine flags, caused warnings
2) link status change information for ethtool was missing
M: 1) use updated driver file with new IRQ flags
2) driver performs periodic link state monitoring and change reporting
-----[ Revision 1.4 ]-----
[ 2009-02-18 14:24:02 by GLeonhardt ]
R:1. use for NIOS2
M.1. possibility of usage without PCI
