Use the new dscp_t type to replace the tos field of struct fib_rt_info.
This ensures ECN bits are ignored and makes it compatible with the
fa_dscp field of struct fib_alias.
This also allows sparse to flag potential incorrect uses of DSCP and
ECN bits.

Since commit 1771afd47430 ("net: cpsw: avoid alignment faults by taking
NET_IP_ALIGN into account") the TI CPSW driver was switched to use correct
define CPSW_HEADROOM_NA to avoid alignment faults, but there are two places
left where CPSW_HEADROOM is still used (without causing issues).
Hence, completely drop CPSW_HEADROOM define and use CPSW_HEADROOM_NA
everywhere to avoid further mistakes in code.

If policy-based routing using the iif selector is used, then the fib
expression fails to look up for the reverse path from the prerouting
hook because the input interface cannot be inferred. In order to support
this scenario, extend the fib expression to allow to use after the route
lookup, from the forward hook.
This patch also adds support for the input hook for usability reasons.
Since the prerouting hook cannot be used for the scenario described
above, users need two rules: one for the forward chain and another rule
for the input chain to check for the reverse path check for locally
targeted traffic.

====================
net: icmp: add skb drop reasons to icmp
In the commit c504e5c2f964 ("net: skb: introduce kfree_skb_reason()"),
we added the support of reporting the reasons of skb drops to kfree_skb
tracepoint. And in this series patches, reasons for skb drops are added
to ICMP protocol.
In order to report the reasons of skb drops in 'sock_queue_rcv_skb()',
the function 'sock_queue_rcv_skb_reason()' is introduced in the 1th
patch, which is used in the 3th patch.
As David Ahern suggested, the reasons for skb drops should be more
general and not be code based. Therefore, in the 2th patch,
SKB_DROP_REASON_PTYPE_ABSENT is renamed to
SKB_DROP_REASON_UNHANDLED_PROTO, which is used for the cases of no
L3 protocol handler, no L4 protocol handler, version extensions, etc.
In the 3th patch, we introduce the new function __ping_queue_rcv_skb()
to report drop reasons by its return value and keep the return value of
ping_queue_rcv_skb() still.
In the 4th patch, we make ICMP message handler functions return drop
reasons, which means we change the return type of 'handler()' in
'struct icmp_control' from 'bool' to 'enum skb_drop_reason'. This
changed its original intention, as 'false' means failure, but
'SKB_NOT_DROPPED_YET', which is 0, means success now. Therefore, we
have to change all usages of these handler. Following "handler"
functions are involved:
icmp_unreach()
icmp_redirect()
icmp_echo()
icmp_timestamp()
icmp_discard()
And following drop reasons are added(what they mean can be see
in the document for them):
SKB_DROP_REASON_ICMP_CSUM
SKB_DROP_REASON_INVALID_PROTO
The reason 'INVALID_PROTO' is introduced for the case that the packet
doesn't follow rfc 1122 and is dropped. I think this reason is different
from the 'UNHANDLED_PROTO', as the 'UNHANDLED_PROTO' means the packet is
fine, and it is just not supported. This is not a common case, and I
believe we can locate the problem from the data in the packet. For now,
this 'INVALID_PROTO' is used for the icmp broadcasts with wrong types.
Maybe there should be a document file for these reasons. For example,
list all the case that causes the 'INVALID_PROTO' drop reason. Therefore,
users can locate their problems according to the document.
Changes since v4:
- rename SKB_DROP_REASON_RFC_1122 to SKB_DROP_REASON_INVALID_PROTO
Changes since v3:
- rename SKB_DROP_REASON_PTYPE_ABSENT to SKB_DROP_REASON_UNHANDLED_PROTO
in the 2th patch
- fix the return value problem of ping_queue_rcv_skb() in the 3th patch
- remove SKB_DROP_REASON_ICMP_TYPE and SKB_DROP_REASON_ICMP_BROADCAST
and introduce the SKB_DROP_REASON_RFC_1122 in the 4th patch
Changes since v2:
- fix aliegnment problem in the 2th patch
Changes since v1:
- introduce __ping_queue_rcv_skb() instead of change the return value
of ping_queue_rcv_skb() in the 2th patch, as Paolo suggested

In order to avoid to change the return value of ping_queue_rcv_skb(),

Meanwhile, make ping_queue_rcv_skb() a simple call to

The current invese logic is harder to follow (and adds extra
tests to the fast path). We have to enumerate all cases which
need to keep the skb before consuming it. It's simpler to
jump out of the full record flow as we detect those cases.
This makes it clear that partial consumption and peek can
only reach end of the function thru the !zc case so move

tls_sw_advance_skb() always consumes the skb at the end of the loop.
To fall here the following must be true:
!async && !is_peek && !retain_skb
retain_skb => !zc && rxm->full_len > len
# but non-full record implies !zc, so above can be simplified as
retain_skb => rxm->full_len > len
!async && !is_peek && !(rxm->full_len > len)
!async && !is_peek && rxm->full_len <= len
tls_sw_advance_skb() returns false if len < rxm->full_len

We track both if the last record was handled by async crypto
and how many records were async. This is not necessary. We
implicitly assume once crypto goes async it will stay that
way, otherwise we'd reorder records. So just track if we're
in async mode, the exact number of records is not necessary.
This change also forces us into "async" mode more consistently
in case crypto ever decided to interleave async and sync.

tls_sw_advance_skb() caters to the async case when skb argument

only call tls_sw_advance_skb() when we actually move past

We plumb pointer to chunk all the way to the decryption method.
It's set to the length of the text when decrypt_skb_update()
returns.
I think the code is written this way because original TLS
implementation passed &chunk to zerocopy_from_iter() and this
was carried forward as the code gotten more complex, without
any refactoring.
The fix for peek() introduced a new variable - to_decrypt
which for all practical purposes is what chunk is going to
get set to. Spare ourselves the pointer passing, use to_decrypt.
Use this opportunity to clean things up a little further.
Note that chunk / to_decrypt was mostly needed for the async
path, since the sync path would access rxm->full_len (decryption
transforms full_len from record size to text size). Use the
right source of truth more explicitly.
We have three cases:
- async - it's TLS 1.2 only, so chunk == to_decrypt, but we
need the min() because to_decrypt is a whole record
and we don't want to underflow len. Note that we can't
handle partial record by falling back to sync as it
would introduce reordering against records in flight.
- zc - again, TLS 1.2 only for now, so chunk == to_decrypt,
we don't do zc if len < to_decrypt, no need to check again.
- normal - it already handles chunk > len, we can factor out the
assignment to rxm->full_len and share it with zc.

mlx5 crypto FPGA code together with inability to configure encryption
keys makes the low steering API completely unusable.
So delete the code, so any ESP flow steering requests will fail with
not supported error, as it is happening now anyway as no device support
this type of API.

The IPSEC_REQUIRED_METADATA capability bit is never set, and can be
safely removed from the flow action flags.

Only FPGA needed this NO_TRAILER flag, so remove this assignment.
