ips : Is FirstBurstSize valid when InitialR2T=yes ?

[Santosh Rao <santoshr@cup.hp.com>]

Hello,

Can someone clarify if the login key FirstBurstSize is valid when :
InitialR2T=yes  and ImmediateData=yes ?

i.e. if immediate data is enabled and un-solicited data is disabled
during login negotiation, is the value of FirstBurstSize received in the
login response to be interpreted ?

My current understanding is that FirstBurstSize is inclusive of the
immediate data portion, and so, if immediate data is enabled, but
un-solicited data is disabled, then, FirstBurstSize *must* be valid and
must be <= DataPDULength. (after rev 09, it would be <=
(MaxRecvPDULength - the header components size)).

For example, a target implementation may offer a FirstBurstSize <
DataPDULength, in which case, the immediate data size is the
MIN(DataPDULength, FirstBurstSize, bytes_to_send).

Can someone clarify if this is a correct interpretation or set me right
on this ?

Thanks,
Santosh
