[E1000-devel] Bug report E1000 driver bonding in 802.3ad mode can not go beyond 1GB/s throughput

[Support T. <su...@ca...>]

Hello,

Intel ada...@ma... recommended us to open a ticket
with you that
your e1000 driver for 82546 chips has throughput limit. With 802.3ad
bonding, the total
throughput of 8 NIC is still 1GB/s, same as single NIC.

Bonding is done by:
# load bonding driver if needed
    if (( ${#eth0[*]} > 1 || ${#eth1[*]} > 1 || ${#eth2[*]} > 1 ||
${#eth3[*]} > 1 || ${#eth4[*]} > 1 || ${#eth5[*]} > 1)) ... ||
          [ "$bond_all" = "YES" ] ; then
        # "miimon" is default for now; set to prevent warning message
        insmod /lib/modules/all/kernel/drivers/net/bonding.o \
            max_bonds=2 mode=802.3ad miimon=100 lacp_rate=fast
    fi

ifenslave bond0 eth0
ifenslave bond0 eth1
ifenslave bond0 eth2
ifenslave bond0 eth3
ifenslave bond0 eth4
ifenslave bond0 eth5
ifenslave bond0 eth6
ifenslave bond0 eth7

Intel adapter support believes this is a bug in the e1000 driver.
Please help.

Thanks!
