Hi All,
Thank you Stephen, Don and Wendy.
We have incorporated feedbacks which have received since after last post.
I'll be resending updated patchset in subsequent emails.
We are working on finding out good way of using tables to manage
compatibility between firmware version number and driver version number.
Kindly review it and feel free to send feedback.
Thanks,
-Amit

More updates needed:
1) diff against 2.6.18-rcX (currently -rc6)
2) remove ifdefs around NETIF_F_TSO
3) remove ifdefs around CONFIG_PCI_MSI
4) during initial allocation of port struct, the following line is
completely superfluous:
port->flags &= ~NETXEN_NETDEV_STATUS
5) netxen_nic_set_multi() does not have any multi-cast filter update code
6) remove impossible checks such as the following in nic_set_promise_mode:
+ if ((phy < 0) || (phy > 3))
+ return -1;
7) the following line in nic_set_mtu requires explanation, or fixing:
+ case NETXEN_NIC_XGBE:
+ new_mtu += 100; /* so that MAC accepts frames > MTU */
8) never call udelay() with a number >= 1000. use mdelay()
9) [major] a great many functions simply do
netxen_nic_do_blah()
case NETXEN_NIC_GBE:
netxen_nic_do_blah_gbe()
break;
case NETXEN_NIC_XGBE:
netxen_nic_do_blah_xgbe()
break;
This is silly and makes the code needlessly larger and needlessly
slower. Modularize the driver to avoid all such functions.
10) don't cast iounmap argument to u8*
11) don't case to/from void*, particularly where you accidentally drop
the __iomem marker:
+ addr = (void *)(adapter->ahw.pci_base + off);
12) make sure the driver passes sparse checks. Read
Documentation/sparse.txt
13) __iomem markers missing in NETXEN_NIC_HW_BLOCK_WRITE_64,
NETXEN_NIC_HW_BLOCK_READ_64
14) If you need a 'void __iomem *' cast in the following macros, there
is a type definition bug somewhere:
+#define NETXEN_NIC_LOCKED_READ_REG(X, Y) \
+ addr = (void __iomem *)(adapter->ahw.pci_base + X); \
+ *(u32 *)Y = readl(addr);
+
+#define NETXEN_NIC_LOCKED_WRITE_REG(X, Y) \
+ addr = (void __iomem *)(adapter->ahw.pci_base + X); \
+ writel(*(u32 *)Y, addr);
+
15) implement NETXEN_NIC_LOCKED_READ_REG, NETXEN_NIC_LOCKED_WRITE_REG,
NETXEN_NIC_HW_BLOCK_WRITE_64, NETXEN_NIC_HW_BLOCK_READ_64 as static
inline functions rather than macros for greater type safety
16) don't invent your own set_bit, clear_bit, etc: _netxen_crb_set_bit
17) don't needlessly invent new types such as
+typedef __le32 netxen_crbword_t; /* single word in CRB space */
18) The strings in netxen_nic_gstrings_test[] should be easily
computer-parseable. Eliminate parens, spaces
19) eliminate magic numbers (replace with named constants) in, e.g.
+ if ((netxen_rom_fast_read(adapter, 0, &n) == 0) && (n &
0x80000000)) {
+ n &= ~0x80000000;
+ if (n < 1024)
20) use the short driver name (commonly DRV_NAME constant in other
drivers) in ETHTOOL_GDRVINFO:
+ strncpy(drvinfo->driver, "NetXen NIC Driver", 32);
21) export the real firmware version in ETHTOOL_GDRVINFO:
+ strncpy(drvinfo->fw_version, NETXEN_NIC_FW_VERSIONID, 32);
22) netxen_nic_set_settings() simply returns success if the NIC is XGBE,
which is obviously wrong
23) bogus return value -1 in netxen_nic_get_eeprom()
24) -EOPNOTSUPP would seem to be a much better return value for XGBE in
netxen_nic_set_pauseparam()
25) netxen_nic_change_mtu() should check minimum MTU too
26) long delays should be sleeping, not spinning the CPU and locking out
other tasks:
+ udelay(10000);
I stopped reviewing here. That should keep you busy...

It looks like you have not run the source throught Lindent as previously
requested. Before you submit the code again, please use the Lindent

I can get the code to ping between two cards. Will be doing more
