Ⅳ. How to reproduce it (as minimally and precisely as possible)

Ⅴ. Anything else we need to know?

1. If applicable, add nginx debug log doc.

QAT驱动计数fw_counter 不是tengine负责写入

有按照文档编译和配置么

有按照文档编译和配置么

参照上述配置的，没看到啥异常。
执行/usr/local/openssl/bin/openssl engine -t -vvvv qatengine 命令也能验证qat配置正确。

如果fw_counter没有计数，那怎么验证tengine使用了qat来做异步卸载ssl呢？
nginx上通过pstack命令查看worker进程实时堆栈，有如下信息：
#0 0x00007fe0dbaae6fd in read () from /lib64/libpthread.so.0
#1 0x000000000054e56e in sock_read ()
#2 0x000000000054cf9a in bread_conv ()
#3 0x000000000054bc65 in BIO_read ()
#4 0x00000000004e9aa7 in ssl3_read_n ()
#5 0x00000000004ee1e7 in ssl3_get_record ()
#6 0x00000000004ebb44 in ssl3_read_bytes ()
#7 0x00000000004f27e0 in ssl3_read ()
#8 0x000000000054516c in async_start_func ()
#9 0x00007fe0db06c010 in ?? () from /lib64/libc.so.6
#10 0x0000000000000000 in ?? ()

@lianglli 能否说明tengine已经在使用qat进行卸载ssl了呢？

QAT驱动计数fw_counter 不是tengine负责写入

QAT_Engine-1.5.0 ，QAT驱动：QAT.L.4.23.0-00001，OpenSSL 1.1.1w
可拿这些版本验证下tengine是否适配支持。
