It may not be noticed since protocols will take care of it. Fix it by

Testing on theadorable (Armada XP) has shown, that using this driver
results in many cache misaligned warning, such as:
CACHE: Misaligned operation at range [7fabd8fc, 7fabd900]
This patch now uses the ALLOC_CACHE_ALIGN_BUFFER() macro to allocate the
buffers on a cache aligned boundary. This fixes all warnings seen on the
Armada XP platform.

eth-uclass.c expects DM-capable Ethernet adapters to implement ops->
read_rom_hwaddr(), or for some other mechanism to set pdata->enetaddr, or
for the user to set environment variable $usbethaddr. Without any of
these, it will refuse to initialize the device since no valid MAC address
is known. Implement this function for the smsc95xx driver.
With this feature implemented, there is no point smsc95xx_init_common()
re-reading the MAC address from ROM, so ifdef out this code when DM_ETH
is enabled.
This allows (at least) the built-in Ethernet on the NVIDIA Harmony board
to operate again.

Commit 147271209a ("net: asix: fix operation without eeprom")
added a special handling for ASIX 88772B that enable another
type of header. This break the driver in DM mode as the extra handling
needed in the receive path is missing.
However this new header mode is not required and only seems to
increase the code complexity, so this patch revert this part of
commit 147271209a.
This also reverts commit 41d1258ace

A previous patch (net: asix: fix operation without eeprom) added a
two-byte shift to the packet buffer when receiving a packet on the
AX88772B.
This shift was not included when the driver was updated to work with
DriverModel. Testing on a Marvell DB-88F6820-ACM showed that the adapter
was not functioning correctly (EHCI timeouts).
This patch brings the two-byte shift to the DriverModel implementation
of ops->recv (asix_eth_recv).
Testing on the same board, we were able to TFTP a file over and confirm
that the crc32 was correct.

Using NAKs on empty RX fifo for bulk in transfers is the right choice
for a interrupt driven model, but U-Boot uses polling and expects an
immediate answer if there is no incoming packet. Using ZLP Bulk In Response
(BIR) mode avoids unexpected timeouts in the host controller driver.
As ZLP mode is reset default, there is no need to set it.

For Ethernet/USB RX packets, the ASIX HW pads odd-sized packets so that
they have an even size. Currently, asix_recv() does remove this padding,
and asic_send() adds equivalent padding in the TX path. However, the HW
does not appear to need this packing for TX packets in practical testing
with "ASIX Elec. Corp. AX88x72A 000001" Vendor: 0x0b95 Product 0x7720
Version 0.1. The Linux kernel does no such padding for the TX path.
Remove the padding from the TX path:
* For consistency with the Linux kernel.
* NVIDIA has a Tegra simulator which validates that the length of USB
packets sent to an ASIX device matches the packet length value inside
the packet data. Having U-Boot and the kernel do the same thing when
creating the TX packets simplifies the simulator's validation.
