ENA default hash configures IPv4_frag hash twice instead of
configure non-IP packets.
The bug caused IPv4 fragmented packets to be calculated based on
L2 source and destination address instead of L3 source and destination.
IPv4 packets can reach to the wrong Rx queue.

ena_flow_data_to_flow_hash and ena_flow_hash_to_flow_type
treat the ena_flow_hash_to_flow_type enum as power of two values.
Change the values of ena_admin_flow_hash_fields to be power of two values.
This bug effect the ethtool set/get rxnfc.
ethtool will report wrong values hash fields for get and will
configure wrong hash fields in set.

The ENA driver tries to open a queue per vCPU.
To determine how many vCPUs the instance have it uses num_possible_cpus()
while it should have use num_online_cpus() instead.

The network device operation for reading statistics is only called
in one place, and it ignores the return value. Having a structure
return value is potentially confusing because some future driver could
incorrectly assume that the return value was used.
Fix all drivers with ndo_get_stats64 to have a void function.

Use setup_timer() instead of init_timer(), being the preferred/standard
way to set a timer up.
Also, quoting the mod_timer() function comment:
-> mod_timer() is a more efficient way to update the expire field of an
active timer (if the timer is inactive it will be activated).
Use setup_timer and mod_timer to setup and arm a timer, to make the code
cleaner and easier to read.

Somehow, I missed a healthy number of ethernet drivers in the last pass.
Most of these drivers either were in need of an updated max_mtu to make
jumbo frames possible to enable again. In a few cases, also setting a
different min_mtu to match previous lower bounds. There are also a few
drivers that had no upper bounds checking, so they're getting a brand new
ETH_MAX_MTU that is identical to IP_MAX_MTU, but accessible by includes
all ethernet and ethernet-like drivers all have already.
acenic:
- min_mtu = 0, max_mtu = 9000
amazon/ena:
- min_mtu = 128, max_mtu = adapter->max_mtu
amd/xgbe:
- min_mtu = 0, max_mtu = 9000
sb1250:
- min_mtu = 0, max_mtu = 1518
cxgb3:
- min_mtu = 81, max_mtu = 65535
cxgb4:
- min_mtu = 81, max_mtu = 9600
cxgb4vf:
- min_mtu = 81, max_mtu = 65535
benet:
- min_mtu = 256, max_mtu = 9000
ibmveth:
- min_mtu = 68, max_mtu = 65535
ibmvnic:
- min_mtu = adapter->min_mtu, max_mtu = adapter->max_mtu
- remove now redundant ibmvnic_change_mtu
jme:
- min_mtu = 1280, max_mtu = 9202
mv643xx_eth:
- min_mtu = 64, max_mtu = 9500
mlxsw:
- min_mtu = 0, max_mtu = 65535
- Basically bypassing the core checks, and instead relying on dynamic
checks in the respective switch drivers' ndo_change_mtu functions
ns83820:
- min_mtu = 0
- remove redundant ns83820_change_mtu, only checked for mtu > 1500
netxen:
- min_mtu = 0, max_mtu = 8000 (P2), max_mtu = 9600 (P3)
qlge:
- min_mtu = 1500, max_mtu = 9000
- driver only supports setting mtu to 1500 or 9000, so the core check only
rules out < 1500 and > 9000, qlge_change_mtu still needs to check that
the value is 1500 or 9000
qualcomm/emac:
- min_mtu = 46, max_mtu = 9194
xilinx_axienet:
- min_mtu = 64, max_mtu = 9000
