Subject: [PATCH net V2 1/2] net: stmmac: Premature loop termination check was ignored on rx
The premature loop termination check makes sense only in case of the
jump to read_again where the count may have been updated. But
read_again did not include the check.
Fixes: ec222003bd94 ("net: stmmac: Prepare to add Split Header support")
