I would try this first -- PHYETH_DISABLE_OFFLOAD="tso gso gro" -- and see if it fixes the problem.
If by chance it does fix it, then it would not be needed in AstLinux 1.4.x. The PHYETH_DISABLE_OFFLOAD settings disable some of the "offload" features of the NICs in an effort to work around this (somewhat obscure) kernel bug. It all kind of makes sense that a particular provider is fragmenting packets in ways others do not, and hits this kernel bug. The PHYETH_DISABLE_OFFLOAD setting above is very "safe", only drawback is it slightly reduces network performance near the 1 Gbps level. BTW, if traffic shaping is enabled this PHYETH_DISABLE_OFFLOAD setting is already applied to external ethernet NIC(s).
