We used both the trans and the trans_pcie structures in
iwl_txq, so we can keep the trans structure instead. This
helps with the refactoring of txq code out of pcie.

When some new clock supports are introduced, e.g. [1]
it might lead to an error although it should be NULL because
clk_init_data is on the stack and it might have random values
if using without initialization.
Add the missing initial value to clk_init_data.

It's an error if the value of the RX/TX tail descriptor does not match
what was written. The error condition is true regardless the duration
of the interference from ME. But the driver only performs the reset if
E1000_ICH_FWSM_PCIM2PCI_COUNT (2000) iterations of 50us delay have
transpired. The extra condition can lead to inconsistency between the
state of hardware as expected by the driver.
Fix this by dropping the check for number of delay iterations.
While at it, also make __ew32_prepare() static as it's not used
anywhere else.

The way Rx queue assignment based on mac address, Ethertype and VLAN
priority filtering operates in I225 doesn't allow us to properly support
NFC rules with multiple matches.
Consider the following example which assigns to queue 2 frames matching
the address MACADDR *and* Ethertype ETYPE.
$ ethtool -N eth0 flow-type ether dst <MACADDR> proto <ETYPE> queue 2
When such rule is applied, we have 2 unwanted behaviors:
1) Any frame matching MACADDR will be assigned to queue 2. It
doesn't matter the ETYPE value.
2) Any accepted frame that has Ethertype equals to ETYPE, no matter
the mac address, will be assigned to queue 2 as well.
In current code, multiple-match filters are accepted by the driver, even
though it doesn't support them properly. This patch adds a check for
multiple-match rules in igc_ethtool_is_nfc_rule_valid() so they are
rejected.

For version 1 to 3 of the device tree, this is the node full
path as a zero terminated string, starting with "/". The
following equation will not hold, since the node name has
been processed in the fdt_get_name().
*pathp == '/'
For version 16 and later, this is the node unit name only
(or an empty string for the root node). So the above
equation will still not hold.
So the kbasename() is redundant, just remove it.
