I link error on 32-bit ARM points to yet another arithmetic bug: drivers/net/ethernet/stmicro/stmmac/stmmac_tc.o: In function `tc_setup_cbs': stmmac_tc.c:(.text+0x148): undefined reference to `__aeabi_uldivmod' stmmac_tc.c:(.text+0x1fc): undefined reference to `__aeabi_uldivmod' stmmac_tc.c:(.text+0x308): undefined reference to `__aeabi_uldivmod' stmmac_tc.c:(.text+0x320): undefined reference to `__aeabi_uldivmod' stmmac_tc.c:(.text+0x33c): undefined reference to `__aeabi_uldivmod' drivers/net/ethernet/stmicro/stmmac/stmmac_tc.o:stmmac_tc.c:(.text+0x3a4): more undefined references to `__aeabi_uldivmod' follow I observe that the last change to add the 'ul' prefix was incorrect, as it did not turn the result of the multiplication into a 64-bit expression on 32-bit architectures. Further, it seems that the do_div() macro gets confused by the fact that we pass a signed variable rather than unsigned into it. This changes the code to instead use the div_s64() helper that is meant for signed division, along with changing the constant suffix to 'll' to actually make it a 64-bit argument everywhere, fixing both of the issues I pointed out. I'm not completely convinced that this makes the code correct, but I'm fairly sure that we have two problems less than before.

Currently a link is declared stale and reset if there has been 100 repeated attempts to retransmit the same packet. However, in certain infrastructures we see that packet (NACK) duplicates and delays may cause such retransmit attempts to occur at a high rate, so that the peer doesn't have a reasonable chance to acknowledge the reception before the 100-limit is hit. This may take much less than the stipulated link tolerance time, and despite that probe/probe replies otherwise go through as normal. We now extend the criteria for link reset to also being time based. I.e., we don't reset the link until the link tolerance time is passed AND we have made 100 retransmissions attempts.

Jianbo Liu says: ==================== Introduce matching on double vlan/QinQ headers for TC flower Currently TC flower supports only one vlan tag, it doesn't match on both outer and inner vlan headers for QinQ. To do this, we add support to get both outer and inner vlan headers for flow dissector, and then TC flower do matching on those information. We also plan to extend TC command to support this feature. We add new cvlan_id/cvlan_prio/cvlan_ethtype keywords for inner vlan header. The existing vlan_id/vlan_prio/vlan_ethtype are for outer vlan header, and vlan_ethtype must be 802.1q or 802.1ad. The examples for command and output are as the following. flower vlan_id 1000 vlan_ethtype 802.1q \ cvlan_id 100 cvlan_ethtype ipv4 \ action vlan pop \ action vlan pop \ action mirred egress redirect dev ens1f1_0 filter protocol 802.1ad pref 33 flower chain 0 filter protocol 802.1ad pref 33 flower chain 0 handle 0x1 vlan_id 1000 vlan_ethtype 802.1Q cvlan_id 100 cvlan_ethtype ip eth_type ipv4 in_hw ... v2: fix sparse warning. ==================== Signed-off-by: NDavid S.

skb_shinfo(skb)->tx_flags is derived from sk->sk_tsflags, possibly after modification by __sock_cmsg_send, by calling sock_tx_timestamp. The IPv4 and IPv6 paths do this conversion differently. In IPv4, the individual protocols that support tx timestamps call this function and store the result in ipc.tx_flags. In IPv6, sock_tx_timestamp is called in __ip6_append_data. There is no need to store both tx_flags and ts_flags in the cookie as one is derived from the other. Convert when setting up the cork and remove the redundant field. This is similar to IPv6, only have the conversion happen only once per datagram, in ip(6)_setup_cork. Also change __ip6_append_data to match __ip_append_data. Only update tskey if timestamping is enabled with OPT_ID. The SOCK_.. test is redundant: only valid protocols can have non-zero cork->tx_flags. After this change the IPv4 and IPv6 logic is the same.
