Dear colleagues, There are filters. Let's have a look on it.
Pretty mode showing: tc -p filter show dev ens5 parent ffff: filter protocol ip pref 49146 u32 chain 0 filter protocol ip pref 49146 u32 chain 0 fh 806: ht divisor 1 filter protocol ip pref 49146 u32 chain 0 fh 806::800 order 2048 key ht 806 bkt 0 terminal flowid ??? not_in_hw match IP protocol 16 match dport 8080 Normal mode showing: tc filter show dev ens5 parent ffff: filter protocol ip pref 49146 u32 chain 0 filter protocol ip pref 49146 u32 chain 0 fh 806: ht divisor 1 filter protocol ip pref 49146 u32 chain 0 fh 806::800 order 2048 key ht 806 bkt 0 terminal flowid ??? not_in_hw match 00100000/00ff0000 at 8 match 00001f90/0000ffff at 20 The string "match 00100000/00ff0000 at 8" looks like is correct since offset up 8 byte from IP Header point is "ip protocol field" But string "match 00001f90/0000ffff at 20" looks like strange, doens't it? Since 20 bytes offset up is IP Header "options field ip". Could somebody explain it to me? -- Best regards, Denis Gubin
