如何从崩溃工具读取数据包丢弃的结果

我有Linux机器红帽7.2

因为eth1接口的丢包问题

我们根据红帽链接进行testing – https://access.redhat.com/solutions/206223

最后我们从崩溃工具中得到如下结果

crash> sym 0xffffffff8152aa5b ffffffff8152aa5b (t) __netif_receive_skb_core+1643 /usr/src/debug/kernel-3.10.0-327.10.1.el7/linux-3.10.0-327.10.1.el7.x86_64/net/core/dev.c: 3587 crash> sym 0xffffffff8152aa5b ffffffff8152aa5b (t) __netif_receive_skb_core+1643 /usr/src/debug/kernel-3.10.0-327.10.1.el7/linux-3.10.0-327.10.1.el7.x86_64/net/core/dev.c: 3587 crash> sym 0xffffffff81597290 ffffffff81597290 (t) __udp4_lib_mcast_deliver+656 /usr/src/debug/kernel-3.10.0-327.10.1.el7/linux-3.10.0-327.10.1.el7.x86_64/net/ipv4/udp.c: 1683 crash> sym 0xffffffff81560b58 ffffffff81560b58 (t) ip_error+104 /usr/src/debug/kernel-3.10.0-327.10.1.el7/linux-3.10.0-327.10.1.el7 .x86_64/net/ipv4/route.c: 938 crash> sym 0xffffffff8151a448 ffffffff8151a448 (T) skb_queue_purge+24 /usr/src/debug/kernel-3.10.0-327.10.1.el7/linux-3.10.0-327.10 .1.el7.x86_64/net/core/skbuff.c: 2413 crash> sym 0xffffffff815d3d7a ffffffff815d3d7a (t) unix_stream_connect+714 /usr/src/debug/kernel-3.10.0-327.10.1.el7/linux-3.10.0-327.10.1.el7.x86_64/net/unix/af_unix.c: 1236 crash> exit 

请帮我理解崩溃的输出,文件path的含义是什么,这意味着文件上的问题是什么?

ifconfig关于每秒增加的丢弃的例子:
