52c5f7b5b4 net/qede/base: reduce verbosity in HW init log
Reduce the verbosity in ecore_pglueb_rbc_attn_handler() while logging
errmsg during HW init. This could happen due to ungraceful exit of
previous driver instance.

124909d7e1 app/testpmd: fix exit for virtio-user
For vdev, just calling rte_eth_dev_close() isn't enough to free all
the resources allocated during device probe, e.g. for virtio-user,
virtio_user_pmd_remove(), i.e. the remove() method of a vdev driver,
needs to be called to unlink the socket file created during device
probe. So this patch calls the rte_eth_dev_detach() for vdev when
quitting testpmd.

vdevs detach on testpmd exit implemented as workaround to fix
a virtio-user issue. The issue was virtio-user cleanup is not
called and existing socket file not cleaned up which will fail
next run.

Added a comment that this workaround should be converted to a proper
cleanup, not something specific to virtio-user, and not something
specific to vdev and testpmd.

a106fcce2c cryptodev: rename functions to get session size
rte_cryptodev_get_header_session_size() and
rte_cryptodev_get_private_session_size() functions are
targeting symmetric sessions.

With the future addition of asymmetric operations,
these functions need to be renamed from *cryptodev_*_session_*
to *cryptodev_sym_*_session_* to be symmetric specific.

The two original functions are marked as deprecated
and will be removed in 18.08, so applications can still
use the functions in 18.05.

The second part of the patch is solved by its own basic
block because it is inside a preprocessor conditional.

Bringing the declaration of the var to the top of the
function would require that also being given its own
preprocessor conditional, or a (void)var to avoid an
unused var warning.  The basic block is no worse than
those imho.

9d0b59f84e mbuf: avoid integer promotion in prepend/adj/chain

        uint16_t data_off;

len (a uint16_t) is promoted to an int using -=.  Do the
subtraction explicitly and cast the result to uint16_t.

The below += or -= changes are solving the same thing.

ef5092e16b mbuf: avoid implicit demotion in 64-bit arithmetic

In function 'rte_validate_tx_offload':
rte_mbuf.h:2112:19: warning: conversion to 'uint64_t'
{aka 'long unsigned int'} from 'int' may change the
sign of the result [-Wsign-conversion]
  inner_l3_offset += m->outer_l2_len + m->outer_l3_len;

  uint64_t inner_l3_offset...

  uint64_t outer_l3_len:9; /**< Outer L3 (IP) Hdr Length. */
  uint64_t outer_l2_len:7; /**< Outer L2 (MAC) Hdr Length. */

We want to do the arithmetic entirely in uint64_t
space, but with the +=, the rhs type becomes int since the
bitfields will fit in int.

Elaborate the artithmetic to be u64 = u64 + int + int, so
the type of the result is correct to be stored in the u64.
