We actually store the MAC address as well as the board_name here.  The
longest board_name is 75 characters so there is more than enough room
to hold the 17 character MAC and the ": " divider.  But making this
buffer larger silences a static checker warning.

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.

Flash template provides instructions to stop, restart and initalize the
firmware. These instructions are abstracted as a series of read, write and
poll operations on hardware registers. Register information and operation
specifics are not exposed to the driver. Driver reads the template from
flash and executes the instructions located at pre-defined offsets.

Template based firmware reset recovery and initialization mechanism minimize
driver changes as firmware evolves.
