failure code over and over.
Also, remove the support for the auto-configuration. I'm not aware of

The pdev->id is used in several places for different purpose. All
these uses assume it's always the id of fec device which is >= 0.
However this is only true for non-DT case. When DT plays, pdev->id
is always -1, which will break these pdev->id users.
Instead of fixing all these users one by one, this patch introduces
a new member 'dev_id' to 'struct fec_enet_private' for holding the
correct fec device id, and replaces all the existing uses of pdev->id
with this dev_id.

Since 92fc43b415, rtl8169_tx_timeout ends up
resetting Rx and Tx indexes and thus racing with the NAPI handler via
-> rtl8169_hw_reset
-> rtl_hw_reset
-> rtl8169_init_ring_indexes
What about returning to the original state ?
rtl_hw_reset is only used by rtl8169_hw_reset and rtl8169_init_one.
The latter does not need rtl8169_init_ring_indexes because the indexes
still contain their original values from the newly allocated network
device private data area (i.e. 0).
rtl8169_hw_reset is used by:
1. rtl8169_down
Helper for rtl8169_close. rtl8169_open explicitely inits the indexes
anyway.
2. rtl8169_pcierr_interrupt
Indexes are set by rtl8169_reinit_task.
3. rtl8169_interrupt
rtl8169_hw_reset is needed when the device goes down. See 1.
4. rtl_shutdown
System shutdown handler. Indexes are irrelevant.
5. rtl8169_reset_task
Indexes must be set before rtl_hw_start is called.
6. rtl8169_tx_timeout
Indexes should not be set. This is the job of rtl8169_reset_task anyway.
The removal of rtl8169_hw_reset in rtl8169_tx_timeout and its move in
rtl8169_reset_task do not change the analysis.

Realtek has specified that the post 8168c gigabit chips and the post
8105e fast ethernet chips recover automatically from a Rx FIFO overflow.
The driver does not need to clear the RxFIFOOver bit of IntrStatus and
it should rather avoid messing it.
The implementation deserves some explanation:
1. events outside of the intr_event bit mask are now ignored. It enforces
a no-processing policy for the events that either should not be there
or should be ignored.
2. RxFIFOOver was already ignored in rtl_cfg_infos[RTL_CFG_1] for the
whole 8168 line of chips with two exceptions:
- RTL_GIGA_MAC_VER_22 since b5ba6d12bd
("use RxFIFO overflow workaround for 8168c chipset.").
This one should now be correctly handled.
- RTL_GIGA_MAC_VER_11 (8168b) which requires a different Rx FIFO
overflow processing.
Though it does not conform to Realtek suggestion above, the updated
driver includes no change for RTL_GIGA_MAC_VER_12 and RTL_GIGA_MAC_VER_17.
Both are 8168b. RTL_GIGA_MAC_VER_12 is common and a bit old so I'd rather
wait for experimental evidence that the change suggested by Realtek really
helps or does not hurt in unexpected ways.
Removed case statements in rtl8169_interrupt are only 8168 relevant.
3. RxFIFOOver is masked for post 8105e 810x chips, namely the sole 8105e
(RTL_GIGA_MAC_VER_30) itself.

ring and 16MB in the tiny packet ring.
We should only fill the jumbo ring once the MTU is increased but
for now halve it's size so it consumes 32MB. Also reduce the tiny
packet ring, with 4 queues we had 16k entries which is overkill.

When transmiting a fragmented skb, qlge fills a descriptor with the
fragment addresses, after DMA-mapping them. If there are more than eight
fragments, it will use the eighth descriptor as a pointer to an external
list. After mapping this external list, called OAL to a structure
containing more descriptors, it fills it with the extra fragments.
However, considering that systems with pages larger than 8KiB would have
less than 8 fragments, which was true before commit a715dea3c8, it
defined a macro for the OAL size as 0 in those cases.
Now, if a skb with more than 8 fragments (counting skb->data as one
fragment), this would start overwriting the list of addresses already
mapped and would make the driver fail to properly unmap the right
addresses on architectures with pages larger than 8KiB.
Besides that, the list of mappings was one size too small, since it must
have a mapping for the maxinum number of skb fragments plus one for
skb->data and another for the OAL. So, even on architectures with page
sizes 4KiB and 8KiB, a skb with the maximum number of fragments would
make the driver overwrite its counter for the number of mappings, which,
again, would make it fail to unmap the mapped DMA addresses.
