The driver assumes that the maximum received buffer for non-jumbo frames is
1536 bytes. But the allocation of the rx fragment doesn't reflect that. It
currently allocates fragments which will only be large enough to be used as
rx buffer with the size of 1534 bytes. This is problematic because the GMAC
will now try to write to 2 bytes which don't belong to its receive buffer
when a large enough ethernet frame is received.
This may already be a problem on existing chips but will at least become a
problem when the 1536 byte rx modus is enabled on MT7621a. It is required
on this SoC to receive ethernet frames which use their full 1500 bytes MTU
and a VLAN header next to the switch VLAN tag.

The length of the DMA rx buffer was always set to 0 because the function
for extracting the length was used to calculate the value for setting it.
Instead the macro has to be split in a get and set function similar to the
TX_DMA_(GET_|)PLEN(0|1) macro.
No problem was noticed on MT7621a before this was changed and thus maybe it
was hidden by different problem which is not yet fixed.

use pktgen to verify on rt3662. can improve transmit rate.

if there is any new tx need to clean up. do it in next napi poll.
collect tx related members to fe_tx_ring struct. for better
cache usage and more readable.

when open device. first ready napi software rx.
then enable hardware interrupt.
final start software tx queue to send data.

the old FE_INT_STATUS register becomes two registers.
FE_INT_STATUS and INT_STATUS. so the hw status almost full
must change to read from FE_INT_STATUS register.
tx/rx done read from INT_STATUS register.
mt7620 datasheet define CNT_GDM1_AF at BIT(29).
but after test it should be BIT(13). why?

- budget is decremented with completed frames, so don't check if done is
smaller
- ACK the interrupt before processing further frames to fix a small race
condition.

The mac address usually write in factory block. but sometime user erase this block , the mac address will change to ff:ff:ff:ff:ff:ff.
This patch is purpose to fix this issue.

* fix TSO features verify on mt7621 firewrt board
* improve tx clean up. no need to access uncached
memory. also use TX_DTX register instead of
read tx ring DONE bit
* mt7621 need napi weight 64 to get more performance
* remove netif_receive_skb, after kernel version
3.7 tcp4_gro_receive can handle tcp checksum.
on rt2880 use iperf tcp LAN to WAN throughput test.
with gro 135 Mbits/sec. without gro 80.4Mbits/sec.

the rx_buf_size now is 1534 when mtu is 1500.
the ethernet frame with vlan tag and FCS is 1522.
so the buffer is enough.

hardware status and tx vlan offload support on all targets
except rt5350. so i modify the IS_ENABLE condition only for
mt7621.
support mt7621 hardware status reference by SDK. but i don't
have mt7621. if not work just set mt7621 FE_REG_FE_COUNTER_BASE
to 0 to let software count.
