Give the step() method a pointer to the containing object, rather than
a pointer to the process. This is consistent with the operation of
interface methods, and allows a single function to serve as both an
interface method and a process step() method.

This reverts commit 15c1200 ("[hermon] Work around missing mport
support in current BOFM implementations").
Signed-off-by: Michael Brown <mcb30@ipxe.org>
Current BOFM versions are unable to create entries with mport>1, which
means that only the port 1 MAC address can be explicitly specified.
Work around this by using the provided MAC address as a base address
for all subsequent ports. For example, if BOFM assigns the address
00:1A:64:76:00:09 for port 1
then we will assign the addresses
00:1A:64:76:00:09 for port 1
00:1A:64:76:00:0a for port 2
Future BOFM versions that may correctly support mport will work with
this scheme without modification provided that the BOFM entries are
created in increasing order of mport. Since BOFM tools tend to
generate entries in increasing order (of slot, port, etc), this is not
an unreasonable compromise.

iPXE operates the forcedeth NIC in promiscuous mode, and never changes
the unicast MAC address filter registers. We should not therefore set
the flag indicating (to other drivers loaded later) that the MAC
address order has already been corrected.

The forcedeth driver currently implements unicast MAC address
filtering in software. This is almost invariably the wrong thing to
do (since the network stack must already be able to cope with unwanted
packets) and it breaks FCoE (which requires the card to operate in
promiscuous mode).
Also, the implementation is buggy: is_local_ether_addr() is used to
check for a locally-assigned Ethernet address (not to check for a
unicast address), and the current link-layer address is in
netdev->ll_addr, not netdev->hw_addr.
Fix by removing this code.

From a cursory examination, it appears as though the calculation of

On reset and close, the ICR register is read to clear any pending
interrupts, but the value is simply ignored. Avoid assigning the
value to a variable, to inhibit a warning from gcc 4.6.
Also fix a potential race condition in reset routines which clear
interrupts before disabling them.

In a virtual environment such as qemu, we can legitimately receive
packets less than 64 bytes in length, such as ARP replies. These are
currently discarded, causing most IPv4 communication to fail.
Fix by ignoring the RFDShort bit when receiving packets.

When chainloading rtl8139.pxe from an old Etherboot rtl8139.zrom, iPXE
can end up misreading the first word of the MAC address from the
EEPROM as being all zeroes. This is presumably because Etherboot has
left the serial EEPROM in an unexpected state.
Fix by using the chip select line to reset the SPI device before we
start accessing it.

The default initiator IQN is "iqn.2000-09.org.etherboot:UNKNOWN".
This is problematic for two reasons:
a) the etherboot.org domain (and hence the associated IQN namespace)
is not under the control of the iPXE project, and
b) some targets (correctly) refuse to allow concurrent connections
from different initiators using the same initiator IQN.
Solve both problems by changing the default initiator IQN to be
iqn.2010-04.org.ipxe:<hostname> if a hostname is set, or
iqn.2010-04.org.ipxe:<uuid> if no hostname is set.
Explicit initiator IQNs set via DHCP option 203 are not affected by
this change.
Unfortunately, this change is likely to break some existing
configurations, where ACL rules have been put in place referring to
the old default initiator IQN. Users may need to update ACLs, or
force the use of the old IQN using an iPXE script line such as
set initiator-iqn iqn.2000-09.org.etherboot:UNKNOWN
or a dhcpd.conf option such as
option iscsi-initiator-iqn "iqn.2000-09.org.etherboot:UNKNOWN"

On 64-bit builds, MLX_DECLARE_STRUCT() produces a structure that is
