Gratuluję wyboru sieciówki Broadcom :P
tu akurat w delu wielkiego wyboru nie miałem :/
Lepiej zrobić ethtool -S eth0. Może coś więcej ciekawe pokaże - jakie typy błędów.

od momentu zmian ta wartość (rx_fw_discards: 60564057) wydaje mi się nie zmieniona. ifconfig terz pokazuje 605745581 i tu rośnie :/
Można obniżyć liczbę składowanych wpisów w nf_conntrack przez zmniejszenie czasu życia wpisów określających nawiązane połączenia TCP.
jeśli chodzi o wpisy w nf_conntrack to mam tak: #v+ net.netfilter.nf_conntrack_generic_timeout = 600 net.netfilter.nf_conntrack_tcp_timeout_syn_sent = 120 net.netfilter.nf_conntrack_tcp_timeout_syn_recv = 60 net.netfilter.nf_conntrack_tcp_timeout_established = 7200 net.netfilter.nf_conntrack_tcp_timeout_fin_wait = 120 net.netfilter.nf_conntrack_tcp_timeout_close_wait = 60 net.netfilter.nf_conntrack_tcp_timeout_last_ack = 30 net.netfilter.nf_conntrack_tcp_timeout_time_wait = 120 net.netfilter.nf_conntrack_tcp_timeout_close = 10 net.netfilter.nf_conntrack_tcp_timeout_max_retrans = 300 net.netfilter.nf_conntrack_tcp_timeout_unacknowledged = 300 net.netfilter.nf_conntrack_tcp_loose = 1 net.netfilter.nf_conntrack_tcp_be_liberal = 0 net.netfilter.nf_conntrack_tcp_max_retrans = 3 net.netfilter.nf_conntrack_udp_timeout = 30 net.netfilter.nf_conntrack_udp_timeout_stream = 180 net.netfilter.nf_conntrack_icmp_timeout = 30 net.netfilter.nf_conntrack_icmpv6_timeout = 30 net.netfilter.nf_conntrack_frag6_timeout = 60 net.netfilter.nf_conntrack_frag6_low_thresh = 196608 net.netfilter.nf_conntrack_frag6_high_thresh = 262144 net.netfilter.nf_conntrack_acct = 0 net.netfilter.nf_conntrack_timestamp = 0 net.netfilter.nf_conntrack_events = 1 net.netfilter.nf_conntrack_events_retry_timeout = 15 net.netfilter.nf_conntrack_max = 262144 net.netfilter.nf_conntrack_count = 123059 net.netfilter.nf_conntrack_buckets = 16384 net.netfilter.nf_conntrack_checksum = 1 net.netfilter.nf_conntrack_log_invalid = 0 net.netfilter.nf_conntrack_expect_max = 256 net.nf_conntrack_max = 262144 #v+
