On 64-bit builds, MLX_DECLARE_STRUCT() produces a structure that is
always a multiple of 64 bits long, causing the HCR structure to be
over-length by one dword. This in turn causes hermon_cmd() to write
beyond the end of the HCR, which causes commands to fail.

Remove duplicate hardware resets, remove network interface logic
reset.
This also fixes a bug where some 3c905C variants would return bogus
EEPROM values because of a too short delay after the network reset.

Most xxx_init() functions are void functions with no failure cases.
Allow pci_vpd_init() to be used in the same way. (Subsequent calls to
pci_vpd_read() etc. will fail if pci_vpd_init() fails.)

Since its implementation several years ago, no driver has used a
fragment list containing more than a single fragment. Simplify the
NVO core and the drivers that use it by removing the whole concept of
the fragment list, and using a simple (address,length) pair instead.

Some SCSI targets (observed with an EMC CLARiiON Fibre Channel target)
will not respond to commands correctly until a TEST UNIT READY has
been issued. In particular, a READ CAPACITY (10) command will return
with a success status, but no capacity data.
Fix by issuing a TEST UNIT READY command automatically, and delaying
further SCSI commands until the TEST UNIT READY has succeeded.

Use individual page mappings rather than a single whole-region
mapping, to avoid the waste of memory that occurs due to the

The current method for ICM allocation exactly matches the addresses
chosen by the old Etherboot driver, but does not match the
specification. Some ICM tables (notably the queue pair context table)
therefore end up incorrectly aligned.
Fix by performing allocations as per the specification.
