We weren't enabling any VLAN features so we missed out on checksum
offload and TSO when using VLANs. Enable them.

It seems like the ehea xmit routine and an ethtool change of TSO
mode could race, resulting in corrupt packets. Checking gso_size
is enough and we can use the helper function.

The num_tx_qps module option allows a user to configure a different
number of tx and rx queues. Now the networking stack is multiqueue
aware it makes little sense just to enable the tx queues and not the
rx queues so remove the option.

commit 18604c548545 (ehea: NAPI multi queue TX/RX path for SMP) added
driver specific logic for exiting napi mode. I'm not sure what it was
trying to solve and it should be up to the network stack to decide when
we are done polling so remove it.
v3:
[cascardo] Fixed extra parentheses.

The ehea driver had some multiqueue support but was missing the last
few years of networking stack improvements:
- Use skb_record_rx_queue to record which queue an skb came in on.
- Remove the driver specific netif_queue lock and use the networking
stack transmit lock instead.
- Remove the driver specific transmit queue hashing and use
skb_get_queue_mapping instead.
- Use netif_tx_{start|stop|wake}_queue where appropriate. We can also
remove pr->queue_stopped and just check the queue status directly.
- Print all 16 queues in the ethtool stats.
We now enable multiqueue by default since it is a clear win on all my
testing so far.

[cascardo] fixed use_mcs parameter description
[cascardo] set ehea_ethtool_stats_keys as const

Remove the deprecated NETIF_F_LLTX feature. Since the network stack
now provides the locking we can remove the driver specific
pr->xmit_lock.

Currently ehea ndo_get_stats can sleep in two places, in a hcall
and in a GFP_KERNEL alloc, which is not correct.
This patch creates a delayed workqueue that grabs the information each 1
sec from the hardware, and place it into the device structure, so that,
.ndo_get_stats quickly returns the device structure statistics block.

Move the IBM drivers into drivers/net/ethernet/ibm/ and make the
necessary Kconfig and Makefile changes.
- Renamed ibm_new_emac to emac
- Cleaned up Makefile and Kconfig options which referred to
IBM_NEW_EMAC to IBM_EMAC
- ibmlana driver is a National Semiconductor SONIC driver so
it was not moved
