Now we have vlan_vids_add/del_by_dev() which serve the same purpose as bond's bond_add/del_vlans_on_slave() with the good side effect of reverting the changes if one of the additions fails. There's only 1 change in the behaviour of enslave: if adding of the vlans to the slave fails, we'll fail the enslaving because otherwise we might delete some vlan that wasn't added by the bonding. The only way this may happen is with ENOMEM currently, so we're in trouble anyway. Signed-off-by:

With GRO/LRO processing, there is a problem because Ip[6]InReceives SNMP counters do not count the number of frames, but number of aggregated segments. Its probably too late to change this now. This patch adds four new counters, tracking number of frames, regardless of LRO/GRO, and on a per ECN status basis, for IPv4 and IPv6. Ip[6]NoECTPkts : Number of packets received with NOECT Ip[6]ECT1Pkts : Number of packets received with ECT(1) Ip[6]ECT0Pkts : Number of packets received with ECT(0) Ip[6]CEPkts : Number of packets received with Congestion Experienced lph37:~# nstat | egrep "Pkts|InReceive" IpInReceives 1634137 0.0 Ip6InReceives 3714107 0.0 Ip6InNoECTPkts 19205 0.0 Ip6InECT0Pkts 52651828 0.0 IpExtInNoECTPkts 33630 0.0 IpExtInECT0Pkts 15581379 0.0 IpExtInCEPkts 6 0.0 Signed-off-by:

Cleanup gfar_start_xmit()'s fast path by factoring out "redundant" FCB insertion code (repeated gfar_add_fcb() calls and related) and by reducing the number of if() clauses (i.e. if(fcb) checks). Improve maintainability (e.g. there's less code and easier to read) also by introducing do_csum and do_vlan to mark the other 2 Tx TOE functionalities, following the same model as do_tstamp. fcb_len may also be 0 now, to mark that Tx FCB insertion conditions (do_csum, do_vlan, do_tstamp) have not been met.

Both [eTSEC76] and [eTSEC12] errata relate to Tx checksum generation (for some MPC83xx and MCP8548 older revisions). They require the same workaround: manual checksum computation and insertion, and disabling the H/W Tx csum acceleration feature (per frame) through Tx FCB (Frame Control Block) csum offload settings. The workaround for [eTSEC76] needs to be fixed because it currently fails to disable H/W Tx csum insertion via FCB. This patch fixes it and provides a common workaround implementation for both Tx csum errata. Signed-off-by:

We're already protected by RTNL lock, so nothing can happen to bond/its slaves, and thus the locking is useless here (both bond->lock and bond->curr_active_slave). Also, add ASSERT_RTNL() both to bond_set_rx_mode() and bond_hw_addr_swap() to catch possible uses of it without RTNL locking. This patch also saves us from a lockdep false-positive in bond_set_rx_mode() vs bond_hw_addr_swap().

Currently we use a lot of time comparison math for arp_interval comparisons, which are sometimes quite hard to read and understand. All the time comparisons have one pattern: (time - arp_interval_jiffies) <= jiffies <= (time + mod * arp_interval_jiffies + arp_interval_jiffies/2) Introduce a new helper - bond_time_in_interval(), which will do the math in one place and, thus, will clean up the logical code. This helper introduces a bit of overhead (by always calculating the jiffies from arp_interval), however it's really not visible, considering that functions using it usually run once in arp_interval milliseconds. There are several lines slightly over 80 chars, however breaking them would result in more hard-to-read code than several character after the 80 mark.

Simple cleanup to not call slave_last_rx() on every time function. It won't give any measurable boost - but looks cleaner and easier to understand. There are no time-consuming functions in between these calls, so it's safe to call it in the beginning only once.

ax88179_tx_fixup() has quite complex code trying to push 8 bytes of control data (len/mss), but fails to do it properly for TCP packets, incurring an extra copy and point of memory allocation failure. Lets use the simple and approved way. dev->needed_headroom being 8, all frames should have 8 bytes of headroom, so the extra copy should be unlikely anyway. This patch should improve performance for TCP xmits. Reported-by:
