treewide: use get_random_u32() when possible

2022-10-11T23:42:58Z

The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

2022-05-11T02:32:20Z

The structure iscsi_conn naming is used by the iSCSI initiator driver. Rename the target conn to iscsit_conn to have more readable code.

cxgb4/chtls/cxgbit: Keeping the max ofld immediate data size same in cxgb4 and ulds

2021-02-15T20:39:33Z

The Max imm data size in cxgb4 is not similar to the max imm data size in the chtls. This caused an mismatch in output of is_ofld_imm() of cxgb4 and chtls. So fixed this by keeping the max wreq size of imm data same in both chtls and cxgb4 as MAX_IMM_OFLD_TX_DATA_WR_LEN. As cxgb4's max imm. data value for ofld packets is changed to MAX_IMM_OFLD_TX_DATA_WR_LEN. Using the same in cxgbit also.
