Combine the ipa_resource_type_src and ipa_resource_type_dst
enumerated types into a single enumerated type, ipa_resource_type.
Assign value 0 to the first element for the source and destination
types, so their numeric values are preserved. Add some additional
commentary where these are defined, stating explicitly that code
assumes the first source and first destination member must have
numeric value 0.
Fix the kerneldoc comments for the ipa_gsi_endpoint_data structure.

Currently, the SDM845 configuration data defines resource limits for
the first two resource groups (for both source and destination
resource types). The hardware supports additional resource groups,
and we should program the resource limits for those groups as well.
Even the "unused" destination resource group (number 2) should have
non-zero limits programmed in some cases, to ensure correct operation.
Add these missing resource group limit definitions to the SDM845
configuration data.

Define a new ipa_resource_group_id enumerated type, whose members
have numeric values that match the resource group number used when
programming the hardware. Each platform supports a different number
of source and destination resource groups, so define the type
separately for each platform in its configuration data file.
Use these new symbolic values when specifying the resource group an
endpoint is associated with. And use them to index the limits
arrays for source and destination resources, making it clearer how
these values are used.

If the number of resource groups supported by the hardware is less
than a certain number, we return early in ipa_resource_config_src()
and ipa_resource_config_dst() (to avoid programming resource limits
for non-existent groups).
Unfortunately, these checks are off by one. Fix this problem in the
four places it occurs.

mlx5-updates-2021-03-24
mlx5e netdev driver updates:
1) Some cleanups from Colin, Tariq and Saeed.
2) Aya made some trivial refactoring to cleanup and generalize
PTP and RQ (Receive Queue) creation and management.
Mostly code decoupling and reducing dependencies between the different
RX objects in the netdev driver.
This is a preparation series for upcoming PTP special RQ creation which
will allow coexistence of CQE compression (important performance feature,
especially in Multihost systems) and HW TS PTP.

Current code uses many different types when dealing with a port of a RDMA
device: u8, unsigned int and u32. Switch to u32 to clean up the logic.
This allows us to make (at least) the core view consistent and use the
same type. Unfortunately not all places can be converted. Many uverbs
functions expect port to be u8 so keep those places in order not to break
UAPIs. HW/Spec defined values must also not be changed.
With the switch to u32 we now can support devices with more than 255
ports. U32_MAX is reserved to make control logic a bit easier to deal
with. As a device with U32_MAX ports probably isn't going to happen any
time soon this seems like a non issue.
When a device with more than 255 ports is created uverbs will report the
RDMA device as having 255 ports as this is the max currently supported.
The verbs interface is not changed yet because the IBTA spec limits the
port size in too many places to be u8 and all applications that relies in
verbs won't be able to cope with this change. At this stage, we are
extending the interfaces that are using vendor channel solely
Once the limitation is lifted mlx5 in switchdev mode will be able to have
thousands of SFs created by the device. As the only instance of an RDMA
device that reports more than 255 ports will be a representor device and
it exposes itself as a RAW Ethernet only device CM/MAD/IPoIB and other
ULPs aren't effected by this change and their sysfs/interfaces that are
exposes to userspace can remain unchanged.
While here cleanup some alignment issues and remove unneeded sanity
checks (mainly in rdmavt),

For interrupt mode INTM=0, TX/RX transfer complete will trigger signal
not only on sbd_perch_[tx|rx]_intr_o (Transmit/Receive Per Channel) but
also on the sbd_intr_o (Common).
As for multi-MSI implementation, setting interrupt mode INTM=1 is more
efficient as each TX intr and RX intr (TI/RI) will be handled by TX/RX ISR
without the need of calling the common MAC ISR.
Updated the TX/RX NORMAL interrupts status checking process as the
NIS status bit is not asserted for any RI/TI events for INTM=1.

When the interface is part of a bridge or an Open vSwitch port and a
packet exceed a PMTU estimate, an ICMP reply is sent to the sender. When
using the external mode (collect metadata) the source and destination
addresses are reversed, so that Open vSwitch can match the packet
against an existing (reverse) flow.
But inverting the source and destination addresses in the shared
ip_tunnel_info will make following packets of the flow to use a wrong
destination address (packets will be tunnelled to itself), if the flow
isn't updated. Which happens with Open vSwitch, until the flow times
out.
Fixes this by uncloning the skb's ip_tunnel_info before inverting its
source and destination addresses, so that the modification will only be
made for the PTMU packet, not the following ones.
