ed3c9a2fca net: tls: make the offload check helper take skb not socket
All callers of tls_is_sk_tx_device_offloaded() currently do
an equivalent of:

 if (skb->sk && tls_is_skb_tx_device_offloaded(skb->sk))

Have the helper accept skb and do the skb->sk check locally.
Two drivers have local static inlines with similar wrappers
already.

While at it change the ifdef condition to TLS_DEVICE.
Only TLS_DEVICE selects SOCK_VALIDATE_XMIT, so the two are
equivalent. This makes removing the duplicated IS_ENABLED()
check in funeth more obviously correct.

2355a6773a cxgb4/chtls/cxgbit: Keeping the max ofld immediate data size same in cxgb4 and ulds
The Max imm data size in cxgb4 is not similar to the max imm data size
in the chtls. This caused an mismatch in output of is_ofld_imm() of
cxgb4 and chtls. So fixed this by keeping the max wreq size of imm data
same in both chtls and cxgb4 as MAX_IMM_OFLD_TX_DATA_WR_LEN.

As cxgb4's max imm. data value for ofld packets is changed to
MAX_IMM_OFLD_TX_DATA_WR_LEN. Using the same in cxgbit also.

9d2e5e9eeb cxgb4/ch_ktls: decrypted bit is not enough
If skb has retransmit data starting before start marker, e.g. ccs,
decrypted bit won't be set for that, and if it has some data to
encrypt, then it must be given to crypto ULD. So in place of
decrypted, check if socket is tls offloaded. Also, unless skb has
some data to encrypt, no need to give it for tls offload handling.

8d174351f2 cxgb4: rework TC filter rule insertion across regions
Chelsio NICs have 3 filter regions, in following order of priority:
1. High Priority (HPFILTER) region (Highest Priority).
2. HASH region.
3. Normal FILTER region (Lowest Priority).

Currently, there's a 1-to-1 mapping between the prio value passed
by TC and the filter region index. However, it's possible to have
multiple TC rules with the same prio value. In this case, if a region
is exhausted, no attempt is made to try inserting the rule in the
next available region.

So, rework and remove the 1-to-1 mapping. Instead, dynamically select
the region to insert the filter rule, as long as the new rule's prio
value doesn't conflict with existing rules across all the 3 regions.

Currently, the hardware TID index is assumed to start from index 0.
However, with the following changeset,

commit c219399988 ("cxgb4: add support for high priority filters")

hardware TID index can start after the high priority region, which
has introduced a regression resulting in connection failures for
ULDs.

So, fix all related code to properly recalculate the TID start index
based on whether high priority filters are enabled or not.

1a91649fd3 net: cxgb4: avoid memcpy beyond end of source buffer
Building with link-time-optimizations revealed that the cxgb4 driver does
a fixed-size memcpy() from a variable-length constant string into the
network interface name:

In function 'memcpy',
    inlined from 'cfg_queues_uld.constprop' at drivers/net/ethernet/chelsio/cxgb4/cxgb4_uld.c:335:2,
    inlined from 'cxgb4_register_uld.constprop' at drivers/net/ethernet/chelsio/cxgb4/cxgb4_uld.c:719:9:
include/linux/string.h:350:3: error: call to '__read_overflow2' declared with attribute error: detected read beyond size of object passed as 2nd parameter
   __read_overflow2();
   ^

I can see two equally workable solutions: either we use a strncpy() instead
of the memcpy() to stop at the end of the input, or we make the source buffer
fixed length as well. This implements the latter.

72a56ca97d crypto: chcr - Fix txq ids.
The patch fixes a critical issue to map txqid with flows on the hardware appropriately,
if tx queues created are more than flows configured then  txqid shall map within
the range of hardware flows configured. This ensure that un-mapped txqid does not remain un-handled.
The patch also segregated the rxqid and txqid for clarity.

578b46b938 cxgb4: add common api support for configuring filters
Enable filters for non-offload configuration and add common api support
for setting and deleting filters in LE-TCAM region of the hardware.

IPv4 filters occupy one slot.  IPv6 filters occupy 4 slots and must
be on a 4-slot boundary.  IPv4 filters can not occupy a slot belonging
to IPv6 and the vice-versa is also true.

Filters are set and deleted asynchronously.  Use completion to wait
for reply from firmware in order to allow for synchronization if needed.
