Check the access by tools for hardware queue engine and handle it
separately than other block registers, otherwise incorrect data
is returned.

All QLogic converged NICs have 128-bit 128MB on card memory.
Fix the limit check from 64MB to 128MB and remove unnecessary
64-bit read/write checks.

The values used by these interfaces are not something you
can interpret any way you want.
They have defined values (from linux/netdevice.h):
enum {
NETIF_MSG_DRV = 0x0001,
NETIF_MSG_PROBE = 0x0002,
NETIF_MSG_LINK = 0x0004,
NETIF_MSG_TIMER = 0x0008,
NETIF_MSG_IFDOWN = 0x0010,
NETIF_MSG_IFUP = 0x0020,
NETIF_MSG_RX_ERR = 0x0040,
NETIF_MSG_TX_ERR = 0x0080,
NETIF_MSG_TX_QUEUED = 0x0100,
NETIF_MSG_INTR = 0x0200,
NETIF_MSG_TX_DONE = 0x0400,
NETIF_MSG_RX_STATUS = 0x0800,
NETIF_MSG_PKTDATA = 0x1000,
NETIF_MSG_HW = 0x2000,
NETIF_MSG_WOL = 0x4000,
};
And you must respect them in your debug logging macros.
You should also use netdev->msg_enable which is there exactly
for this purpose, and then you can use the netif_msg_*()
helper macros.
Look at how any other driver implements these interfaces. It's always
better to look at the most popular drivers to see how interfaces are
meant to be used, rather than looking at an interface and trying
to figure out what clever things specific to your driver you can
do with it. :-)
Please either fix this up or eliminate this patch from your
patch set. Please resubmit this entire set once you've
fixed this problem.
Thanks.

Interface should be visible even if resource allocation fails.
netif_device_attach should be called for every netif_device_detach.
