Subject: [PATCH 01/10] net: thunderx: Cleanup duplicate NODE_ID macros, add
nic_get_node_id()
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
reworking the node calculation.

Subject: [PATCH 07/10] net: thunderx: fix nicvf_set_rxfh()
This fixes a copypaste bug that was discovered by a static analysis
tool:
The patch 4863dea3fab0: "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
522 nicvf_config_rss(nic);
523 return 0;
524 }

No need to cast void* to u8*: pointer arithmetics
works same way for both.
