if_bridge turns off checksum offload of members?

Hi,

May be a stupid questions, but:

1) There are zero matches of IFCAP_TOE in kernel sources .. there is not 
support for TOE in 7.0, but may be this is work in progress for 8-current?
2) In #define BRIDGE_IFCAPS_MASK (IFCAP_TOE|IFCAP_TSO|IFCAP_TXCSUM) - 
TOE should be repleaced with RXCSUM or just removed?
3) Why RX is never checked? In my case this doesn't matter because em 
turn off both TX and RX if only one is disabled, but probably there is a 
hardware,
that can separate them e.g. RX disabled while TX enabled?
4) I'm not sure why bridge should not work with two interfaces one of 
which support TX and the other does not? At least if I turn on checksum 
offload
only on one of the interfaces the bridge is still working ...

P.S. I saw very good results with netisr2 on a kernel from p4 before few 
months .. are there any patches flying around so I can test them with 
7-STABLE? :)
