Switching back to LDD transactions from LDWB.
While transmitting packets out with LDWB transactions
data integrity issues are seen very frequently.

This bug pops up with NetworkManager on Fedora 21. NetworkManager tends to
stop the interface (nicvf_stop() is called) before changing settings. In
stopped state MAC cannot be sent to a PF. However, when the interface is
restarted (nicvf_open() is called), we ping the PF using NIC_MBOX_MSG_READY
message, and the PF replies back with old MAC address, overriding what we
had after MAC setting from userspace. As a result, we cannot set MAC
address using NetworkManager.
This patch introduces special tracking of MAC change in stopped state so
that the correct new MAC address is sent to a PF when interface is reopen.

This fixes a copypaste bug that was discovered by a static analysis
tool:
The patch 4863dea3fa: "net: Adding support for Cavium ThunderX
network controller" from May 26, 2015, leads to the following static
checker warning:
drivers/net/ethernet/cavium/thunder/nicvf_ethtool.c:517
nicvf_set_rxfh()
warn: we tested 'hkey' before and it was 'false'
drivers/net/ethernet/cavium/thunder/nicvf_ethtool.c
506 /* We do not allow change in unsupported parameters */
507 if (hkey ||
^^^^
We return here.
508 (hfunc != ETH_RSS_HASH_NO_CHANGE && hfunc !=
ETH_RSS_HASH_TOP))
509 return -EOPNOTSUPP;
510
511 rss->enable = true;
512 if (indir) {
513 for (idx = 0; idx < rss->rss_size; idx++)
514 rss->ind_tbl[idx] = indir[idx];
515 }
516
517 if (hkey) {
^^^^
So this is dead code.
518 memcpy(rss->key, hkey, RSS_HASH_KEY_SIZE *
sizeof(u64));
519 nicvf_set_rss_key(nic);
520 }
521

There are duplicate NODE_ID macro definitions. Move all of them to
nic.h for usage in nic and bgx driver and introduce nic_get_node_id()
helper function.
This patch also fixes 64bit mask which should have been ULL by

The driver is on the pci bus and thus requires the Thunder PCIe host
