Christoph Paasch found netxen could trigger a BUG in its dismantle
phase, in netxen_release_tx_buffer(), using full size TSO packets.
cmd_buf->frag_count includes the skb->data part, so the loop must
start at index 1 instead of 0, or else we can make an out
of bound access to cmd_buff->frag_array[MAX_SKB_FRAGS + 2]
Christoph provided the fixes in netxen_map_tx_skb() function.
In case of a dma mapping error, its better to clear the dma fields
so that we don't try to unmap them again in netxen_release_tx_buffer()

It is werid that qlge driver supports NETIF_F_TSO6 but
not NETIF_F_IPV6_CSUM. This also causes some kernel warning [1]
when VLAN device setups on a qlge interface.
I think the qlge hardware doesn't support NETIF_F_IPV6_CSUM,
so we have to just remove the NETIF_F_TSO6 flag.
After this patch, the TCP/IPv6 traffic becomes normal again,
no kernel warnings any more.
NOTE: I only tested it on 2.6.32 kernel, even if the upstream
kernel could fix this automatically (it is hard to track NETIF*
flags), removing it is also safe.

The function qlcnic_probe() return 0 for success and negative value
for most of its internal tests failures. There is one exception
that is error case going to err_out_free_netdev:. For this error case,
the function abort its success execution path, but returns non negative
value, making it difficult for a caller function to notice the error.
This patch fixes the error case that do not return negative value.
This was found by Coccinelle, but the code change was made by hand.
This patch is not robot generated.
A simplified version of the semantic match that finds this problem is
as follows: (http://coccinelle.lip6.fr/)
