This patch updates ixgbe_setup_phy_link_generic to set/unset
auto-negotiation for all speeds. This ensures that unsupported
speeds are unset. This is necessary since the PHY NVM may
advertise unsupported speeds.

In case of mlx5e_open_rq fails the error handling will jump to
label err_close_xdp_sq and will try to close the xdp_sq unconditionally.
xdp_sq is valid only in case of XDP use cases, i.e priv->xdp_prog is
not null.
To fix this in this patch we test xdp_sq validity prior to closing it.
In addition we now close the xdp_sq.cq as well.

Currently, the Rx and Tx fifos are evenly allocated between the hardware
queues of the device. As more queues are instantiated, the fifo memory
needs to be able to be allocated based on queue priority. This allows for
higher priority queues to have more fifo memory than lower priority
queues. Prepare for this by modifying the current fifo calculation to
assign the fifo queue allocation in an array that is then used to program
the hardware.

Now that we have setters to configure the port's MAC, use them to
refactor the port setup and adjust_link code.
Note that port's MAC speed, duplex or RGMII delay must not be changed
unless the port's link is forced down. So wrap all that in a
mv88e6xxx_port_setup_mac function.

While the two bits for link, duplex or RGMII delays are used the same
way on chips supporting the said feature, the two bits for speed have
different meaning for most of the chips out there.
Speed value is stored in bits 1:0, 0x3 means unforce (normal detection).
Some chips reuse values for alternative speeds when bit 12 is set.
Newer chips with speed > 1Gbps reuse value 0x3 thus need a new bit 13.
Here are the values to write in register 0x1 to (un)force speed:
| Speed | 88E6065 | 88E6185 | 88E6352 | 88E6390 | 88E6390X |
| ------- | ------- | ------- | ------- | ------- | -------- |
| 10 | 0x0000 | 0x0000 | 0x0000 | 0x2000 | 0x2000 |
| 100 | 0x0001 | 0x0001 | 0x0001 | 0x2001 | 0x2001 |
| 200 | 0x0002 | NA | 0x1001 | 0x3001 | 0x3001 |
| 1000 | NA | 0x0002 | 0x0002 | 0x2002 | 0x2002 |
| 2500 | NA | NA | NA | 0x3003 | 0x3003 |
| 10000 | NA | NA | NA | NA | 0x2003 |
| unforce | 0x0003 | 0x0003 | 0x0003 | 0x0000 | 0x0000 |

Driver allocates replacement buffers before-hand to make
sure whenever an aggregation begins there would be a replacement
for the Rx buffers, as we can't release the buffer until
aggregation is terminated and driver logic assumes the Rx rings
are always full.
For every other Rx page that's being allocated [I.e., regular]
the page is being completely mapped while for the replacement
buffers only the first portion of the page is being mapped.
This means that:
a. Once replacement buffer replenishes the regular Rx ring,
assuming there's more than a single packet on page we'd post unmapped
memory toward HW [assuming mapping is actually done in granularity
smaller than page].
b. Unmaps are being done for the entire page, which is incorrect.
