Marvell Ethernet IP supports PHY negotiation driven by HW. This

This driver doesn't appear to support vlan acceleration at
all. However, it does claim to support TSO and IP checksums
for vlan devices. Thus any configured vlan device would
end up passing down partial checksums or TSO frames.
The driver also uses the value from skb->protocol to
determine TSO and checksum offload information, but assumes
that skb->protocol holds the l3 protocol information.
As a result, vlan traffic with partial checksums or TSO
will fail those checks and TSO will not happen.
Fix this by using vlan_get_protocol() helper.

Mbit/s. However, the MVPP2_GMAC_CONFIG_MII_SPEED bit in the

Mbit/s operation. This commit therefore fixes 10 Mbit/s operation.

Now that all the users of mvpp2_bm_bufs_free() have been fixed, we can safely
clean the function prototype.
The function is always called to release all the buffers in a BM pool, and
the number of buffers freed is not needed. Therefore, we change the return
to a void, and remove the "num" parameter. This is a cosmetic change, to
make the code slightly cleaner.

After a call to mvpp2_bm_bufs_free(), the caller usually wants to know
if the function successfully freed the requested number. However, this
cannot be done by looking into the BM pool count, because the current
buffer count was updated by mvpp2_bm_bufs_free().
In fact, the current callers of mvpp2_bm_bufs_free() use it to release
all the buffers in the pool, so we can fix this by simply checking
if the pool is not empty.

Currently, the network interfaces that are not configured by the bootloader
(using e.g. tftp or ping) can detect the link status but are unable to
transmit data.
The network controller has a functionality that allows the hardware to
continuously poll the PHY and directly update the MAC configuration accordingly
(speed, duplex, etc.). However, this doesn't work well with phylib's
software-based polling and updating MAC configuration in the driver's callback.
This commit fixes this issue by:
1. Setting MVPP2_PHY_AN_STOP_SMI0_MASK in MVPP2_PHY_AN_CFG0_REG in
mvpp2_init(), which disables the harware polling feature.
2. Disabling MVPP2_GMAC_PCS_ENABLE_MASK bit in MVPP2_GMAC_CTRL_2_REG in
mvpp2_port_mii_set() for port types other than SGMII.

As reported by Maggie Mae Roxas, the mvneta driver doesn't behave
properly in 10 Mbit/s mode. This is due to a misconfiguration of the
MVNETA_GMAC_AUTONEG_CONFIG register: bit MVNETA_GMAC_CONFIG_MII_SPEED
must be set for a 100 Mbit/s speed, but cleared for a 10 Mbit/s speed,
which the driver was not properly doing. This commit adjusts that by
setting the MVNETA_GMAC_CONFIG_MII_SPEED bit only in 100 Mbit/s mode,
and relying on the fact that all the speed related bits of this
register are cleared at the beginning of the mvneta_adjust_link()
function.
This problem exists since c5aff18204 ("net: mvneta: driver for
Marvell Armada 370/XP network unit") which is the commit that
introduced the mvneta driver in the kernel.
