Yes it can be shorten,
msp->t_clk = 133000000;
msp->tx_csum_limit = 9 * 1024;
if (pd) {
if (pd->t_clk) msp->t_clk = pd->t_clk ;
if (pd->tx_csum_limit) sp->tx_csum_limit = pd->tx_csum_limit;
}
pd->t_clk
i was thinking about that in my first posting but i have the feeling that ppl
tend to overlook the "if (pd)" but in this case it is important since the
behavier is different.
IMHO it would be better to make sure that pd->t_clk,pd->tx_csum_limit have usefull
values than adding a check but this is up to the maintainer.
