  1. uadk: wd_find_drv with drv_name and alg_name 

    Add wd_find_drv to find drv with drv_name and alg_name,
considering several drivers supporting same alg.

Also add UADK_ALG_ADAPT to compat with init2 interface

  2. uadk: add adapter to support multi-accelerators 

    Interface:
	uadk_adapter_alloc;
	uadk_adapter_free;
	uadk_adapter_set_mode;
	uadk_adapter_attach_worker;
	uadk_adapter_parse;
	uadk_adapter_config

Supported mode: round-robin, threshold

  3. Adding zlib drv to simulate cpu instruction driver 

    In order to simulate cpu instruction accelerator, this patch adds
zlib drv, which does not require accelerator at all.
So may not require wd_xxx_init, and ctx and sched which relates
to queue.

Btw, zlib is required.
apt-get install zlib1g-dev

  4. uadk/alg: let UADK_ALG_SOFT register to uadk 

    Will use hisi_zlib to test adapter, so let UADK_ALG_SOFT register to uadk

  5. hack: move length to the head of msg 

    Threshold mode need get msg length from msg, and compare length
with threhold to decide using hardware or software accelerator.

However msg struct are not same.
Hack move length to the head of msg.

Hack with digest, cipher, aead: in_bytess

struct wd_rsa_req: __u32 src_bytes
struct wd_ecc_req: __u32 src_bytes
struct wd_dh_msg: ?
struct wd_comp_msg: __u32 in_cons?

  6. uadk/digest: use adapter 

    init interface switch to adapter
init2 interface use adapter for MIX mode

Test:

uadk_tool test --m sec --digest 0 --sync --optype 0 --pktlen 16 \
	--keylen 16 --times 1 --multi 1

uadk_tool test --m sec --digest 0 --sync --optype 0 --pktlen 16 \
	--keylen 16 --times 1 --multi 1 --init 2

  7. wd_comp: use adapter via init2 

    Switch to adapter interface via init2 interface

Test:
uadk_tool benchmark --alg zlib --mode sva --opt 0 --sync --pktlen 1024 \
	--seconds 1 --multi 1 --thread 1

Test
only hisi_zlib
only hisi_zip
Both hisi_zlib and hisi_zip, using round-robin as default mode.

  8. wd_comp: decompress complete when length are consumed 

    driver can only update length
 msg->produced = msg->req.dst_len - strm.avail_out;
 msg->in_cons = msg->req.src_len;
status is decided by caller

// not sure about this patch,
with this patch, compress and decompress are both OK

./sample/uadk_comp --optype 0 --alg gzip <src >out
./sample/uadk_comp --optype 1 --alg gzip <out >dst
vimdiff src dst

  9. sample/uadk_comp: use init2 interface 

    switch to init2 interface, which use adapter

Test:
func()
{
	uadk_comp  --optype 0 --alg $1 <src >out
	uadk_comp  --optype 1 --alg $1 <out >dst
	vimdiff dst src
}
func gzip
func zlib

  10. wd_comp: test threshold 

    use hisi_zip if >= threshold
use hisi_zlib if < threshold

Test:

uadk_tool benchmark --alg zlib --mode sva --opt 0 --sync \
	--pktlen 1024 --seconds 1 --multi 1 --thread 1
uadk_tool benchmark --alg zlib --mode sva --opt 0 --sync \
	--pktlen 10240 --seconds 1 --multi 1 --thread 1
